Ran two small tournaments to see if I could discern any difference between the stock Fruit and one with Delta and Futility pruning enabled. I wish I had more time, this is all I could do for now. I'll let you be the judge of the results and games. Settings: Pentium 3 1.2GHz, ponder off, 64mb hash per engine, time control was 3 1, Perfect v6.1 book was used and set to "optimize". Fruit v2.1 with no changes: 34.0 Shredder 9 30.5 Fritz 8 Bilbao 30.0 Fruit 2.1 25.5 Junior 9 Download the games from that tournament here: ftp://spdycpu.dyndns.org/f21default-tourney.zip Fruit 2.1 with Delta and Futility pruning enabled: 33.5 Fruit 2.1 33.5 Shredder 9 32.0 Fritz 8 Bilbao 21.0 Junior 9 Download the games from that tournament here: ftp://spdycpu.dyndns.org/f21delta-tourney.zip Not definitive proof of anything, but I think it is starting to show a small trend that delta and futility pruning helps.
