Some call issues #61

Closed cbrt729 closed 2 years ago

  1. The following hand can get to a mangan tenpai by calling pon and discarding 5p. Since we only have to consider pon and kan in 3 player mode, the combination seems simple. 
    ##### OWN TURN #####
Debug String: 4p|33344588p45677s||111z||919m67z1p9s9p1m|27z9m2s1m4s1p63z24p|9m9p356z1m2z2p9s6z|0,0,0|3|1|21
Right Player Tenpai Chance: 50.2%, Expected Hand Value: 17721
Left Player Tenpai Chance: 11.5%, Expected Hand Value: 11823
Strategy: General
Consider call on 4p
Could not find combination. Call declined!
  2. The AI accepted the call despite folding on the next discard. The log shows the left player's tenpai chance somehow increased on the discard phase.

I hotfixes the second part of this issue in the master branch. It was a problem related to 3 player mode. I'm currently improving the decision to make calls overall. Once call-improvements is finished the first part of the issue will also be solved.
