Method Summary

boolean	canPlayGame(GamePlay game) canPlayGame() returns true only if the Player provides an applicable heuristic for the type of game given.
double	heuristic(GamePlay game, GameMove move, int[] role) This function - often used as a callback function - evaluates the given move in the context of the given game; it is expected to return quickly.
void	setRandomSeed(long seed) randomizes the heuristics with the given seed.

Method Detail

setRandomSeed

public void setRandomSeed(long seed)

randomizes the heuristics with the given seed. By default, randomization is disabled; you can disable randomization through this method by using 0 as the seed parameter. Every other number will initialize the internal randomizer.

canPlayGame

public boolean canPlayGame(GamePlay game)

Description copied from interface: Player

canPlayGame() returns true only if the Player provides an applicable heuristic for the type of game given. This way, a player can control whether it can a game.

 //Example:
 if (game instanceof MyGameClass) return true; else return false;
 // or:
 if (game.getClass() == myFavoriteGame.getClass()) return true; else return false;
 

heuristic

public double heuristic(GamePlay game,
                        GameMove move,
                        int[] role)

Description copied from interface: Player

This function - often used as a callback function - evaluates the given move in the context of the given game; it is expected to return quickly. This function is really the only function that contains proprietory knowlege about the game (as all other functions could be implemented generically without domain knowlege; this is why the class TemplatePlayer provides already most methods except this function for easy implementations of this interface); heuristic() asks for a heuristic of the move given the game status - treating the status as a leaf in a potential search tree (whereas evaluate() may perform a game tree search before returning a value).
