TeeDee won it's first game against any other program with this
against the current GNU 5.07, after the addition of an implementation
of your late move reduction addition. All prior games were crushes
for GNU 5.07, prior to this game.
What used to be about equal depth between the two went to much
more selective for TeeDee with the deeper variations seen in the
PGN below.
Your late move reduction history pruning appears to have impact!
Thankyou for sharing your method clearly and understandably. It
was quite exciting to watch this game!
GNU's evaluation function is much more complex than the very
simplistic material+pcsq+mobility of TeeDee.
The code was:
#ifdef LATEMOVEREDUCTION
// late move reduction, i.e. the poorly named history pruning, follows.
if (prune == 0 && extension == 0 && reduction == 0 && legals > 3 &&
!(sml[mvi].cap!=0||sml[mvi].pro!=0||
hheuristic[stm][sml[mvi].from][sml[mvi].to]>0))
extension=-1;
#endif
I have enclosed the game for posterity. No books were used. No pondering.
No EGTB.
