Subject: History Heuristic

Author: Larry Griffiths

I have been reading about the History Heuristic and have seen pro's and con's
about it.

I plan on implementing it to see what happens.  This heuristic is related to
killer moves and uses the from and to squares in a 64 x 64 array to maintain
history information when moves are bestmoves or cutoffs.  Each entry has 2 to
the depth power added to it when a bestmove or cutoff is found.

Would you recommend the History Heuristic, and has anything changed for the
better with the method described above?

Thanks in advance.

Larry.
