Perhaps it could be better to watch how the score is changing when game
goes on. If it keeps on going more and more negative (opponent capturing
program's pieces one after another) the game could be resigned.

I think if computer is still having enough pieces to mate incautious
opponent, it shouldn't resign.

My program never resigns. Perhaps it could, if it has only king alone
against opponents army. BUT there are always the possibility for stalemate.
One can sometimes find beautiful sequence of moves leading to stalemate
in a "lost" game. Or perpetual checks or ...

Summa summarum:  NEVER resign!
