I repeated the same idea, although only for 1/2, that I did for 10.18. If you remember, with 10.18, cutting the search time by 1/2 (leaving opponents at normal time, which simulates cutting cpu speed by 50%) reduced 10.18 by 70 Elo, and halving that reduced it by another 80.
For 23.4, here are the two numbers:
Code: Select all
Crafty-23.4-1 2666 4 4 30000 61% 2576 20%
Crafty-23.4-2 2664 4 4 30000 61% 2576 21%
Crafty-23.4-3 2567 3 3 30000 50% 2576 21%
I did not do the 1/4 speed run (yet). Got side-tracked trying to get gnuchess 5.07 to run on the cluster. Seems (so far) it is not quite protocol version 2 complaint, refusing to send "move xyz" and insisting on "my move is xyz". I don't want to hack my referee so am looking at gnu to see if I somehow overlooked something. It is responding to the protover 2 correctly, but it isn't sending the move correctly...
