But in any case, if they used mtd(f), then we didn't see the "real fritz" play chess here, because mtd(f) is also not quick and dirty to implement. It requires lots of algorithm changes, it *definitely* requires significant hash-table changes, and so forth. Seems like they were too interested in going faster, but overlooked difficulties in getting stronger. > >He also told me that they had tried out the SMP-Crafty on that machine >and that he thinks that there are still bugs in the parallel code: he had >seen a PV ending in mate, but with a value of 2.xx ! > >I told him that my program had played against a Crafty 15.10 (Killerchess) >and that that Crafty had spoiled a drawn rook ending into a loss, and >that it would be an explanation if that Crafty also ran on 2 processor NT >machine. > >But then games started: you seem to know more from them than me as >a spectator.
