I mean what >hash does it use? the form is adaptive NPS hashmin hashmax phashmin phashmax The NPS is an estimate of the NPS crafty will hit on your hardware. It doesn't have to be that accurate, but the more accurate the better. hashmin/hashmax are the min and max hash settings you want to see. Crafty will tune the hash value between those limits, after computing the estimated nodes searched (based on the estimated NPS you supply, plus the time control being used when xboard/winboard send the "level command" over.) Ditto for phash. This lets you give a range, and crafty will choose the best value based on your estimated speed, and the time control being played. I mainly did it for ICC so that long games can use big hash values, without using big hash for all games which can cause some paging if you are running other things on the computer at the same time and fire up a really "big hash" crafty for an ICC game. > I used to know that hash and hashp are used for setting the hash, but this >"adaptive" seems an alternative. Is an alternative or something else......? Yes. Don't do both. Adaptive gives a pretty good size setting, but lets you give a min and max to prevent swapping on a fast but small-memory machine... > > >>> >>>> >>>> >>>>>ponder off >>>>>swindle on >>>>>learn 7 >>>>>book random 1 >>>>>bookw freq 0.7 >>>>>bookw ratio 0.9 >>>>>bookw eval 0.7 >>>>>bookw learn 1 >>>>>bookw cap 0.5 >>>>>book width 4 >>>>>book on >>>>>show book >>>>>kibitz 1 >>>>>computer >>>>>exit >>>>>-------- >>>> >>>> >>>>All looks pretty normal.
