proj4.SmartPlayer

public class SmartPlayer
extends java.lang.Object

A smart(er) TicTacToe player. It keeps track of moves it has already made, and when it can tries take the one that has resulted in the most wins. Failing that, it will take an action that has resulted in the least losses. If all actions are equal, it will choose one at random. This object must be told when a new game has started (and what player it is playing) and also it must see the game when it is finished (otherwise there is no way for it to know if an option resulted in a win or a loss. This class must have a Hashtable that maps TicTacToe boards to statistics about the results of the game
