Tic Tac Toe allows because of the simplicity and very limited number of possible game variations a full brute force search. Here the advanced variation of mini max search alpha beta is used to additionally reduce the search space.
You can find the search intelligence source in AlphaBetaSearch.java in package ch.evolutionsoft.game.tictactoe.treesearch.
The Tic Tac Toe portlet uses a Primefaces 7.0 JSF implementation to interact with users.
