Here, my Python 3 version of the Markov chain
It is a simple project with a Markov model, and a random number generator for the first turn.
I play 5 matchs with 10 rounds against the AI:
Human / AI / equality
6 / 4 / 0
3 / 5 / 2
2 / 3 / 5
5 / 2 / 3
4 / 5 / 1
An other match :
WARNING: The model is not unbeatable. The 25 rounds are useful because they allow the robot to "calibrate" itself. After about ten epochs, the bot becomes relatively interesting. (some modifications will come)
