Mastermind game(using Bayesian approach) not sure if this is how i would approach it

[lotrsimp12345]

I plan on using the Bayesian method to try and solve the mastermind problem. The user will enter 4 numbers which represent the colors on the board from 6 different colors. After which the computer will randomly estimate the posterior probabilities for all events. ?Then continue with this scheme until it has gone through 12 rounds or guesses the score?. An event is defined as a row that the codebreaker uses.
