Larry Kaufman:
Actually we already have enough improvements that we could release a Komodo 6 tomorrow with enough elo gain to catch Houdini 2, at least at IPON level or slower.
The only reason we don't do so is our commitment to Komodo MP; if we released K6 sp first many would doubt that MP would ever come out! Here are some test results of latest version ON WINDOWS, without benefit of an optimized (PGO) compile.
Blitz (5' + 3" on each thread of Intel 16 core machine):
vs. Houdini 1.5 + 9.5 elo (2574 games)
vs. Critter 1.6 + 8.6 elo (3224 games)
vs. Stockfish 2.3 +57.8 elo (1463 games)
Rapid (30' + 18" as above) vs. Houdini 1.5 + 16.7 elo (1621 games)
Since Houdini 2 is only a few elo stronger than 1.5, and since we will gain several more elo from an optimized compile, I feel pretty confident in saying that we have at least caught up with Houdini 2 now except for bullet chess. Note also the improvement with longer time limits (at 1' we are still behind Houdini 1.5). The same trend is apparent on Linux in tests vs. Critter.
