reversi-demo

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;
   }
