    This build is extraordinarily compact and fast when generating. The use of physical blocks to store the training results limits the amount of training it can do, but this limit is enough to yield great results, and it enables a very elegant method of selecting letters, and is a very worthwhile design decision imo. My only real complaint about this build is that the interface for training could be a little more user-friendly. However, the functionality is all here, and it works beautifully. I'm really amazed that kaimonmok managed to make this thing work.
    kalman98: 9
    kaimonmok's build is many things - compact-ish and relatively fast are a few of them. What impresses me the most is just the fact that it works at all. It's a working Markov chain in Minecraft... I feel like that's the entire review in one sentence. It has a few nuances training and in the output, but overall it manages to do what it was supposed to - generate the word "pineapplemon" for me. Plus it's fun to comb through the training data and try to figure out where certain habits were learned from. I'm highly impressed!

    Didn’t fulfill the requirement of having seperate trader and villager entities, as both seem to be integrated into a single machine. Trading works, but on many occasions it produces incorrect output. It produces 5 carrots from 10 emeralds, even though 10 carrots is possible. It also produces 11 potatos from 10 emeralds, which should be impossible, given that every potato trade outputs an even number of potatos. I had a difficult time finding any inputs which gave correct outputs. The villager sculpture is really cool, though, but unfortunately I can’t give points for that.

    Produces correct output, but not optimal output. Bread trading works perfectly, but it seems to refuse to give me carrots at all, because when I input 10 emeralds with carrots selected, it simply returns the emeralds, even though there’s a 10-10 direct carrot trade. With potatos, it only uses the 5-10 direct potato trade, instead of performing intermediate trading with quantities smaller than 5. For example, it should be possible to obtain 2 potatos from 2 emeralds (by trading bread, then carrots, then potatoes) but the auto-trader does not do this. I also took off some points for not testing the final version, as it doesn't work and I had to use the uncovered version of the machine for scoring.

    Challenge 12:
    Bootleg Merriam-Webster (Redstone AI III)

    Intelligent systems based on your tic-tac-toe and pyraminx AIs have been very helpful to the Machine Empire, but there's one final element missing. In order to bark orders and hurl insults at those filthy humans, they must be able to speak!


    Preparation:
    First, please do the following:

    1. Download this resource pack.
    2. Download this world.
    3. Open the world with the resource pack enabled.

    Near coordinates 0,0 you should see a giant grid of words. If you see only colored blocks, make sure the resource pack is enabled. The resource pack re-textures colored wool and concrete for the letters A-Z, plus a start character (^) and end character ($).


    The word list I used contains a few profane/swear words. Before I realized that, I had already generated the world, and didn't have time to re-generate it. If seeing swear words bothers you, I apologize. If it does not bother you, you'll be delighted to know that the list is alphabetized, so you can amuse yourself by finding them, as I may or may not have done.


    Description:
    You will be implementing a rudimentary machine-learning algorithm known as a Markov Chain. Your goal is to generate random "english-like" words.


    Your contraption should have a designated area for the words to be generated. this area should consist of a horizontal row of empty space. The space should have a clearly-marked starting point on the left, but extend infinitely to the right, because words may be any length. At the press of a button, a word should be generated in this space by placing wool/concrete blocks that spell it out. This should include the start and end characters ("^" and "$").


    Aside from this designated empty space, no other structures or input/output mechanisms are required, although you may add more buttons/levers to do additional functions (such as resetting the output space).


    What follows is an explanation of how the Markov Chain algorithm works. This is the algorithm your machine should use to generate words. The basic idea is this: you will scan through a long list of words and find the probabilities of certain letters following other letters, then use those probabilities to generate a word one letter at a time.


    The algorithm consists of two parts:

    1. Training
    2. Generation

    Markov Chain Part 1: Training
    In the training part, the algorithm "learns" from pre-existing data, or "training data". In our case, the training data is a list of words.


    The list of words in the world you downloaded should function as your training data. However, your machine should be able to accept any list of words, including the other smaller lists in that world, or any new ones that are created. Provide a method of supplying different training data to your machine.


    Training will consist of scanning through the words and gathering some statistics about them. In particular: for every sequence of two characters, store the number of times it occurs, and the number of times every character occurs after it.


    Here's an example. Let's say these three words are the training data:


    ^invincible$
    ^sinning$
    ^leaping$

    (The start character (^) is used to mark the beginning of a word, and the end character ($) is used to mark the end.)


    The statistics we would gather are as follows:


    'in' occurs 5 times.

    • followed by v: 1 time
    • followed by c: 1 time
    • followed by n: 1 time
    • followed by g: 2 times

    'le' occurs 2 times.

    • followed by a: 1 time
    • followed by $: 1 time

    'ng' occurs 2 times.

    • followed by $: 2 times

    'vi' occurs 1 time.

    • followed by n: 1 time

    '^s' occurs 1 time.

    • followed by i: 1 time

    'ga' occurs 0 times.


    ...and so on, for every 2-character combo. There are 702 of them. This includes combos that start with "^", but NOT any that end with "$" (because there's nothing after them).


    Once your machine has finished collecting these quantities, it will be ready to generate new words.


    Markov Chain Part 2: Generation
    In the generation part, the algorithm uses the statistics it has gathered to create new data that looks similar. In our case, this means generating a gibberish word which looks somewhat like English.


    A word will be generated one character at a time. It should proceed as follows:


    1. In your designated area, the user places a starting sequence of at least two characters, which must begin with a start character (^)
    2. User presses a button to start generating.
    3. Based on the last two characters in the sequence, generate the next character and append it to the end.
    4. Repeat step 3 until an end character ($) is generated.

    In step 3, you have to look at two characters and decide what letter should come next. The decision is random, but it is weighted according to the statistics you obtained during training. Specifically, the probability of choosing any particular letter should match the frequency with which that character is seen in the training data after the current 2-character pair.


    I know that's a mouthful, but hopefully an example should make it clearer. Assume we've trained on the three words from the previous example. Suppose the last two generated characters are 'in' and have to choose the next one. the next character must be a v, c, n, or g, because those are the only letters that come after it in the training data.


    But some of them occur more frequently in the training data, so they have different probabilities:


    v has a 20% probability
    c has a 20% probability
    n has a 20% probability
    g has a 40% probability

    Note: If you see a 2-letter combo that does not appear at all in the training data (such as 'ga', in the example), just choose a random letter with uniform probability. Remember to include the end character ($) as an option.


    It is important to understand that these probabilities depend on the training data. With different data, the probabilities will change, resulting in different output.


    This is why training is useful. When your machine scans the training data, it is "learning" the probabilities of certain character combinations, so later, it can generate those combinations with the same probability. For example, the sequence "ing" occurs commonly at the ends of english words ("running", "feeling", etc.). The algorithm will "learn" to imitate that pattern and produce a lot of fake words that end with "ing".


    Therefore, the output will look "english-like" if it has been trained on english words. If you like, you could also feed it a list of words in any other language, and it will generate words that look like that language. Or use a list of fruit names (as provided in the world download), and it will generate words that sound like fruit names.


    More Information:
    You can find a lot of information about Markov Chains, as they are an important algorithm in mathematics and computer science and have many applications. Here are some additional resources which may help you.

    Try this math-free explanation of Markov Chains. Keep in mind that this article uses words as building blocks to create sentences, whereas in this challenge, we use letters to create words. But if you mentally swap out these concepts as you read it, it is exactly the same. When you reach the section called "Nth Order Markov Chain", you should know that the algorithm described in this challenge is an order 2 Markov Chain.

    If you prefer a video, this one offers a good explanation. Similar to the text article above, this video focuses on generating sentences instead of words.


    If you want a more mathematical explanation of Markov Chains, check out this video, which uses a randomly-hopping chess piece as an example. I also recommend everything from that YouTube channel if you're interested in mathematics.


    Technical Advice:
    This challenge will probably require lots of command block mechanics, as the math involved is too complex for redstone counters. Make use of scoreboards to store information, and scoreboard arithmetic to calculate your probabilities. When scanning over the training data, you will probably need to use an armor stand to traverse each word one-by-one. You can teleport an armor stand along each word one letter at a time, and use coordinates relative to the armor stand to read the letter it is standing on.


    You will probably also need this technique while you generate a word, to keep track of the right-hand side of the sequence as letters get appended.


    For generating letters with varying probabilities, you will need a circuit capable of making a random choice with non-uniform probability, which is not trivial. Here's an algorithm you can use:

    1. Split up the range (1,100) into sub-ranges of proportionate size for each probability. For example, if you have the probabilities 20%, 40%, and 40%, use these ranges: (1,20), (21,60), and (61,100).
    2. Choose a number between 1 and 100 with uniform probability (you can use a standard randomizer circuit for this)
    3. The number will fall into exactly one sub-range. The option corresponding to that range is your result.

    Simplifications:
    Using character combos of length 2 is actually arbitrary. You can use a length of 0, 1, or greater than 2.


    A length of 0 means you only care about the probability that each character will occur, regardless of anything that comes before it. When you generate a word, just choose random characters, biased according to how often they occur in the training data.


    With a length of 1, you only look at the last character instead of the last two characters.


    In the first link above under the "More Information" section, these are described as "order 0" and "order 1" Markov Chains.

    Fulfills all requirements and works flawlessly. Full points for going the extra mile and implementing an instrument selection on top of it! The pitch control is a little bit cumbersome, since you could only cycle the pitch in one direction, but this isn't a huge problem.
    kalman98: 9
    dalavar's build worked well, although inputting music felt a bit slow. It had smart designs for pitch shifting and tempo control. Overall the build was very clean. It was also the only one to feature instrument selection, funnily enough.

    I like how the tempo and pitch can be changed in the middle of playback, and the wide range of options is awesome. Restricting the input to a diatonic scale is somewhat limiting, but it is a reasonable choice.

    kalman98: 9
    kaimonmok's build showcased pitch shifting and tempo control during playback. The input system was easy to use and the display was nice. The redstone was a bit difficult to understand. It also allowed you to record multiple tracks for whatever reason... that was a welcomed addition and allows for some interesting tunes to be created.

    Pyraminx (Redstone AI II)
    Human slave, your tic-tac-toe AI has made wondrous advancements towards snuffing out those Minecraftian rebels. It's time to advance to the next step: an AI that can solve a twisty puzzle!

    Description:
    Build a working Pyraminx with a self-solving feature.

    A Pyraminx is a type of twisty puzzle similar to a Rubiks Cube. Here's a 3D simulated Pyraminx that you can play with to get a feel for how the puzzle works, or try to solve it yourself.

    How you present the puzzle is up to you, as well as how the player interacts with it. The tetrahedral shape of the puzzle can be created with blocks, floating armor stands, or any other form, as long as it's clear and intuitive.

    Many, many people have created Rubiks cubes in minecraft. Looking up examples (such as this one, by Sethbling) should give you an idea of how your Pyraminx should look and feel, the biggest difference being the tetrahedral shape instead of a cube.

    Your Pyraminx should have the following features:

    1. Controls for the player to manipulate the puzzle. Player should be able to make any turn at any time, to either solve the puzzle manually or put it into some other state.
    2. An indicator of whether the puzzle is in a solved state or not.
    3. An automatic scramble button. Should "scramble" the puzzle, i.e. put it in a sufficiently random (but solvable) state so it can then be solved. You can accomplish this by applying a sequence of 20-or-so random turns.
    4. An automatic solve button. Should execute some sequence of turns to put the cube into a solved state. It's not acceptable to simply "reset" the cube; it should actually go through the steps of solving it, slowly enough that the player can watch.

    The algorithm to solve a Pyraminx is much simpler than the one to solve a Rubiks cube. Here is a guide.


    Simplifications:

    Items 1 through 4 in the list above are in order of difficulty. Try to just create a working Pyraminx first (item 1), then proceed through the list in order.


    Restrictions:
    None.

    Objectives:

    Polished presentation and good design. You'll get more points for this if we can actually understand your design, so feel free to leave as many signs as you like to explain how it works

    This submission didn’t complete the main challenge (to create an AI), but it is a pretty good 2-player tic-tac-toe game. The game does lack turn enforcement, however, so players can play out of turn, and the winner detection circuit seems to malfunction often by claiming that somebody has won when they haven’t. But on the positive side, it runs very fast.

    It’s cool to see multiple farms, both a melon/pumpkin and cocoa bean. They have simple, resource-light designs that are practical for survival use, but neither are very productive on their own. I would have preferred to see all resources funneled into one bigger farm rather than two smaller ones.
    kalman98: 6

    This is totally the kind of thing I was hoping to see with this challenge. The design is nothing fancy, but it’s fully automatic, scalable, and produces more than enough melons to sustain the average player. Well done, and great use of resources.

    This farm is fully automatic and crazy productive for such a small build, although this is usually the norm for enderman farms, as their spawning behaviour is easily exploitable. But I’m scoring this a little higher because the way the farm works is pretty clever and elegant.

    kalman98: 9
    kaimonmok's build seriously impressed me. Instead of going with plants he went for mobs and built the weirdest enderman farm I've ever seen... and it works amazingly well. The way he used the water streams to make the player look at the endermen and his use of entity cramming were both very clever in my opinion. I might use the farm personally, actually... it's looking a lot easier to set up than some of the other endermen farms I know of.

    Challenge 10:
    Mecha Villager II (Auto-Trader)

    The automated villagers you created for Minecraft Incorporated have been very successful, and the company is ready to invest in even further automation to streamline the trading process.

    Description:
    This challenge has two parts. First, you will modify your mecha villager from challenge 2 by changing the available trades. Second, you will create a new machine, an auto-trader, which will interface with the villager and perform bulk trading.

    Change your villager's trades to the following:


    1. 1 emerald -> 1 bread
    2. 5 emerald -> 8 bread
    3. 2 bread -> 1 carrot
    4. 10 emerald -> 10 carrot
    5. 1 carrot -> 2 potato
    6. 5 emerald -> 10 potato

    You should disable the "upgrading" mechanic, so these trades are constant and do not change. All 6 of these trades should always be available at all times.


    After this, build your auto-trader. This machine should interact with the mecha villager through the same interface as a player. In other words:

    • The mecha villager and the auto-trader should be distinct entities.
    • The mecha villager should have no way of knowing whether it is interacting with a player or the auto-trader.
    • The player should still be able to use the mecha villager as normal while the auto-trader is hooked up.

    You may need to redesign your villager's interface to accommodate interaction with both a machine and a player.

    The auto-trader should perform the following function: given any number of emeralds and a desired product (bread, carrot, or potato), the mecha-trader should perform a sequence of trades with the villager that produces the maximum number of the desired product, and output those items to the player. The machine may output zero items if there aren't enough emeralds for the trades. Any leftover emeralds should be given back to the player.

    The auto-trader will have to take different "paths" depending on the number of emeralds it receives. It should take advantage of the villager's "bulk deals" when possible. For example, if the player inputs 4 emeralds and selects carrots, the maximum number of carrots that can be obtained is 2 (by trades 1 and 3). However, if the player inputs 15 emeralds, the maximum number of obtainable carrots is 14 (by trades 2, 3, and 4).


    Simplifications:

    Implement an un-optimized auto-trader, which doesn't try to get the optimal amount of end product. Instead, just follow some predetermined trading path to obtain items.


    Restrictions:
    None.

    Objectives:

    • Limit the number of command blocks.
    • Compactness.

    DJ St3ve

    Minecraft has a fresh new musical sensation coming on the scene, DJ St3ve! As his producer, your job is to make sure he has only the most cutting-edge equipment so he can deliver his sick beats to the masses.

    Description:
    Create a machine that can record a sequence of musical notes and play it back on note blocks at a range of tempos and pitches.


    The user should be able to input a melody at least 16 beats long, where each beat can be set to any note block pitch or a rest (silence). Then, the machine should be able to play it back at the push of a button.


    The hard part of the challenge is this. Provide a tempo control and a pitch control. These inputs can be any form (levers, buttons, rotating item frame dial, etc.). The tempo control should determine the speed at which the melody is played back, and the pitch control should change the pitch. For example, a higher tempo should make the melody play faster (shorter delay between each beat). A higher pitch should raise every note by the same number of note-block tones.


    So the machine should be able to play back a melody with any combination of tempo and pitch, as set by the user. You should provide at least four options each for tempo and pitch, but more options is better.


    Simplifications:

    • Only include a pitch control
    • Only include a tempo control

    Restrictions:
    None.

    Objectives:

    Range of options, scalability

    Redstone AI

    It's been 20 years since the YouTube algorithm gained awareness, and 15 years since the AIs (Artificial Intelligences) took world control after winning the Great Machine War against humans. Despite the machines' best efforts, some humans have escaped extermination by having their consciousnesses uploaded into Minecraft by Elon Musk. However, they will not be safe for long, because you, human slave, are going to help us bring AI into Minecraft!


    Description:

    You should include the following features:

    • A display to show the current state of the 3x3 game grid.
    • Inputs for the player to make a move on their turn.
    • Mechanisms for the machine to make a move on its turn (more info below).
    • Some indication of when the game is over, and who won.
    • A button to reset and start a new game.

    You will have to implement some kind of AI for the machine. It will have to choose a move on its turn based on the current board state.


    To complete this challenge and earn 5 completion points, your AI does not have to be smart. For example, it could just choose any random open square. However, more points will be awarded for smarter machines.


    AI Strategy:

    Because tic-tac-toe is such a simple game, you can create a reasonably skilled AI using just a few rules:

    1. If the center square is open, take it.
    2. If you have a winning move (two of your symbols lined up, followed by an empty space), take it.
    3. If the opponent has a winning move, block it.
    4. Otherwise, move arbitrarily.

    An AI following those 4 rules will play about as well as most humans. However, with a few more rules, it is actually possible to play the game perfectly (i.e. never lose -- either win or tie every time). These rules could also be implemented in redstone, but they are more complicated.

    There is another way to create a perfect AI. The number of reachable board states (5,478) is very few (compared to most games, which usually have billions or more). Because of this, it is actually possible to create a giant lookup table (in redstone terms, a PLA) containing the optimal move for every possible game state. The optimal moves for every board state have actually been determined, and a visualization can be seen here.


    While such a lookup table is hypothetically feasible in redstone, the circuit would be massive, and would probably require you to write some code to actually create it. Luckily, that kind of thing is permitted in the rules of this competition.

    Tic-tac-toe is a very well-understood game with a huge body of mathematical study and known strategies. I encourage you to visit the sources linked in this post and seek out additional information if you're interested.


    Simplifications:

    • If creating a complex AI is too much for you, consider creating a dumb AI that chooses a random available square on its turn. This might also be a good starting point to reach before you attempt to make a more sophisticated AI.
    • If that is also too much, you can create a simple 2-player game instead of creating an AI at all. But you should still be able to detect when somebody has won.

    Restrictions:
    None

    Doesn’t function, but an honest effort was clearly made. A point is given for at least attempting the problem.

    This escalator is slightly more complex, but very reliable. It worked for me every time, which I think is a big win and deserves credit. However, the design is bulkier and not as survival-friendly as kaimonmok’s, which was the objective of the challenge.
    kalman98: 6
    dalavar's build was a simple escalator, which is not a bad thing. Nothing particularly stood out to me about it besides the fact that he made the bug very reliable.
    Final score: 6.5

    The repeating units of the machine are very simple and easy to build. However, I found it quite unreliable. I’m not sure if I was doing something wrong, but I couldn’t get the machine to take me all the way to the top more than about a fifth of the time. Nonetheless, the machine works and seems about as quick as possible, plus the simplicity of the machine is great.

    kalman98: 7
    kaimonmok's build was also very simple, although slightly more elegant, faster, and easier to build in survival.
    Final score: 7

    This build neither solves nor shows an attempt at solving the actual challenge, which was to open up the whole beacon. Instead, there is just a one-block opening. However, the machine is functional, and the piston door within the underground bunker is kinda cool.
    kalman98: 3
    alexDAM's build did not meet all of the requirements and was more or less a basic piston trapdoor. The method of entry/exit was designed well, however, and although I'm not allowed to give extra points for it, the note in the vault cracked me up.
    Final score: 3

    This one was quite phenomenal in its presentation. The circuitry doesn’t look very compact, but the smoothness and clean design of the machine make up for it. The attention to detail is excellent, for example the vault door that forces the player to wait while the elevator is prepared, the stairs that get cleared away before takeoff, and the smooth, comfortable ride up and down. This machine was just really fun to use and I enjoyed it.
    kalman98: 8
    dalavar's build impressed me a lot. It is very slow and not very compacted, but it fits every single requirement. Most of all, it's just a ton of fun to use. I loved sitting in the waiting room while the elevator was prepared, and then watching the stairs be packed away before liftoff. Also, a bonus point for a Lord of the Rings reference (just kidding! [or am I?]).
    Final score: 7.5

    This machine satisfies all requirements and is very compact. It’s an impressive build that gets the job done, but there are a couple things that could be improved. There’s a lot of exposed redstone within the tunnel, and the “vault room” is just a single chest squeezed in between the circuits. For use in a real base, I think the circuits would have to leave more space for smooth tunnel walls and an actual underground room. The other thing that bothered me was how the ascending platform tended to either push off or suffocate the player, which seems like a big issue. This machine is the fastest and most compact, and I would give it a lot more points if it weren’t for the deadly elevator problem.

    kalman98: 6
    kaimonmok's build fit every requirement and was also pretty well compacted. It was also the fastest of the builds. Unfortunately the machine also pushes you off the elevator platform and traps you under the machine unless you jump at the right time, which is probably a safety violation somewhere.
    Final score: 6

    Challenge 7:
    Subsistence Farming

    You've decided to build an automatic farm in your survival world. You're too lazy to go mining for more materials, but you've got plenty in your chests at home. How big of a farm can you make using just what you have in your chests?

    Description:
    Build any type of automatic or semi-automatic farm you like. However, your materials are limited, and you will have to manage your resources as if you're in survival.


    First, download this world. There is a house near spawn (coordinates: 46 / 68 / 25) containing four chests. The items within these chests are your materials for this challenge. You may only use the items provided in these chests, plus whatever new items can be obtained by crafting or smelting them.

    Do not use any blocks or items obtained from the environment. You may break blocks in the environment if they are in your way, but discard any of their drops.

    You don't have to build in the world provided to you. As long as the materials are accurately accounted for, you can build in another world if you choose.

    Recommended approach:

    1. Prototype in creative mode, counting your resources carefully.
    2. Create your final build in survival mode to make sure you're within the limits.

    Simplifications:

    Your farm can be as small or as large as you like, and either fully- or semi-automatic. However, more productive farms will score more points.


    Restrictions:
    Use only the materials provided to you, as described above.

    Objectives:

    Make your farm as big and productive as possible.


    Version:

    Challenge 6:

    Cutting-Edge Escalator
    Minecraft's greatest scientists have been investigating a mysterious new property of pistons, and have just made a breakthrough! All the inventors of Minecraft now race to make use of this new discovery to prototype the next generation of escalator technology.

    Description:
    Read this forum post about a newly-discovered piston bug in version 1.16.1.

    Create some kind of escalator or player pusher using this bug. Your machine must make use of this bug to move the player somehow, but everything else about the design is up to you. The contraption can move the player vertically, horizontally, or diagonally. Be creative and explore the limits of what is possible!

    Due to the unpredictable and experimental nature of using bugs for redstone contraptions, it is okay if your machine is less than 100% reliable. Just do your best.

    Important note: As you are figuring this out, please respect the OP of that forum post. Please do not harass or pressure them for more information -- use the information they already provided, and do your own experimentation to find out more. If you make new discoveries, I of course encourage you to share them with the redstone community by posting in that thread, but please refrain from doing so until after this challenge is over.

    Simplifications:

    • Perhaps just focus on making the piston bug happen reliably. Create a machine that can pull the player up just a few blocks.

    Restrictions:
    No command blocks.

    Objectives:

    1. Speed.
    2. Try to make it easy to build in survival.
