I've seen a lot of algorithms for how to play this, Donal Knuth has one that can win in 5 moves, but none that are really usable by humans. The method I use, which seems to always win is: Guess Depending how many 1's were right, Guess , , , Continue in this manor until the solution is found. Have been meaning to simulate this and see if there are any games where this method would not work. Sometimes it takes all the moves but I've never lost. It always returns a solution in a small number of guesses. On Android the free app "Simon Tatham's Puzzles" has an implementation of Mastermind and this is the same algorithm I use to solve it.

But minimax doesnt work for hidden state games. How to solve the "Mastermind" guessing game?

Mastermind is a board game based on deduction where the player must discover a combination of colors with a minimum of guesswork. The game is generally played with 2 players with asymmetric functions: one is an encoder, the other is a decoder.

Originally released back in Mastermind has become a classic abstract strategy game. The basic premise of the game is that one player creates a four color code in secret. The other player then has to try and figure out the code by making guesses. After each guess the player who made the code gives you information. They will give you key pegs for each correct color and for colors that are in the correct spaces. The goal is to figure out the code as quickly as possible. For more details on how to play the game, check out our Mastermind How to Play guide. Most players play Mastermind where they make random guesses. By randomly guessing you usually will be able to figure out the code before you run out of guesses. This is a fun way to play the game, but it is far from optimal.

CyberDildonics 43 days ago root parent next [—] Why are you assuming anything, just learn how the game works. Start with a text file of every combination separated by lines. Hacker News new past comments ask show jobs submit. Otherwise, delete from the set E all the codes that would give the same answer. One for colors that aren't there. It claims that expands things to 59, possibilities. Generate guesses from the filtered list then add to the filters. Guessing at random from the solution space converges surprisingly quickly. The encoder must respond by indicating whether one or more colors are correctly or incorrectly placed. So its not really hidden state, despite the player not knowing the initial conditions. However, the person above posted that mastermind actually is a hidden state game because the player does not a-priori know the state of the hidden rule. With 6 colors and 4 choices you get possibilities. The solution space is fairly small so I would start with a random guess then, of all solutions that are still legal, pick the one that would -- at worst -- reduce the solution space the most essentially a one move ahead minimax. If the decoder finds the combination of the encoder, the game ends. Need Help?

Follow the sequence shown in the grey block above and put it into the game.

What are you talking about here? CyberDildonics 41 days ago root parent next [—]. So that's what I was discussing. My friend also gave presentations on some solutions in rust, that I attended twice. This algorithm can find the code in 5 steps or less. One for colors that aren't there. Guessing at random from the solution space converges surprisingly quickly. You must be thinking of a different game. CyberDildonics 42 days ago root parent next [—] You don't need to be well versed in reinforcement learning "a-priori" knowledge or worry about opponents moves or "optimal tabular and minimax solutions" or branching factors or anything else. Write to dCode! Thank you! However, not all players reason with mathematical algorithms, it is possible to imagine harder to find combinations by trapping the human brain.
