NAME
reversi-demo - a self-playing reversi demo using GGTL
SYNOPSIS
reversi-demo reversi-demo SIZE reversi-demo SIZE PLY reversi-demo SIZE PLY TRACEPLY
DESCRIPTION
This shows how simple it is to create a self-playing Reversi (aka
Othello) program with the GGTL reversi(3) extension. If you have GGTL
installed, a program called "reversi-demo" should have been installed
with it.
If invoked without arguments (or with only some of the arguments
given), the defaults for SIZE, PLY and TRACEPLY are 6, 3, and -1.
SOURCE
- The full source for "reversi-demo" is:
- #include <stdio.h>
#include <stdlib.h>
#include <ggtl/reversi.h> - int main(int argc, char **argv)
{RState *state;
GGTL *g;
int size;
int ply;
int trace;size = argc > 1 ? atoi(argv[1]) : 6;
ply = argc > 2 ? atoi(argv[2]) : 3;
trace = argc > 3 ? atoi(argv[3]) : 1;
if (size % 2) {size++;}state = reversi_state_new(size);
g = reversi_init(ggtl_new(), state);
ggtl_set(g, TYPE, FIXED);if (!g && !state) {puts("cannot allocate enough memory");
return EXIT_FAILURE;}ggtl_set(g, PLY, ply);
ggtl_set(g, TRACE, trace);
do {reversi_state_draw(state);
putchar('\n');
state = ggtl_ai_move(g);} while (state);if (0 == ggtl_eval(g)) {puts("game ended in a draw");}
else {state = ggtl_peek_state(g);
printf("player %d %s\n", state->player,0 < ggtl_eval(g) ? "won" : "lost");}ggtl_free(g);
return 0;}
