AI finds optimal positions

  • @slow

In order to win ASAP

As an AI player

I want to place my numerical marks in the optimal positions

  • Numeric marks indicate sequence positions that the AI player X should find and mark.
  • Alphabetic marks indicate sequence positions that the player O will mark when it is its ply.
  • X marks have previously already been analyzed and can therefore be placed on the initial board in any order.
  • O marks can be placed on the initial board in any order.
  • * indicates the optimal winning position that the AI player X should find based on the marks of player O.
  • The scenario number indicates the alternating sequence numbers of how player X and O place their marks in this game.
  • Based on Wikipedia optimal decision tree for player X in Tic-Tac-Toe without:
    • the two draws
    • reduced requirements for: 1342, 1347, 1423, 1523, 1652, 1659, 1723, 1832, 193274
