Go up one level in this thread


Rajen,

If both programs were given the same computers with ponder-on there would be
essentially no change in performance relatively. The moves would probably be
better.  The only way to determine any difference in performance is to play
Program A with ponder-on against itself on an identical computer with
ponder-off.  I would think that a 30 to 75 ELO point improvement would be seen
on the program running with ponder-on since it would be thinking almost twice as
long.

The more expensive way of doing this would be to pay a 2600 level GM to play
games against your program with both on/off ponder.

PS I think that Sarah Bird may have done this experiment.
