NAME

ggtlai - the various AIs supported by GGTL

SYNOPSIS

  #include <ggtl/core.h>
  
  /* set the current AI type */
  ggtl_set(g, TYPE, X);
  /* get the current AI */
  ggtl_get(g, TYPE);
  /* force a move */
  ggtl_move(g, m);
  /* make the current AI perform a move */
  ggtl_ai_move(g);

DESCRIPTION

GGTL supports a few different modes for the AI player. The various AIs can be chosen by calling ggtl_set(g, TYPE, <type>). The accepted types are:

NONE

Not really an AI. Always picks the first move returned by the get_moves() callback. Can be useful for testing.

RANDOM

Not really an AI either. Picks one of the available moves at random. It is the responsibility of the user to call srand() to make sure the random generator is seeded differently for each run.

FIXED

Performs a fixed-depth Alpha-Beta search to find the best move at a given ply (depth in the game tree). The depth to be searched can be set with ggtl_set(g, PLY, depth).

ITERATIVE

This AI performs an iterative deepening Alpha-Beta search to find the best possible move at the greatest depth that can be searched in a given time. The time allowed for a search can be set with ggtl_set(); use ggtl_set(g, TIME, 0.350) to set the allowed time to 350 milliseconds.
