The "cap" value refers to the CAP project Dann has all the epd data for. These are most book positions searched to fairly significant search depths. This is just a weight to tell Crafty how much to factor in the CAP scores (if available) when choosing book lines... > > Also is the following Crafty.RC settings good for running Crafty against other >Chess-engines and not humans(i know that the only difference would make sense in >comp-comp or hum-comp is the "computer" command, but anyway).....? >Also anything to add or remove to inrease strength? :-) (I think i know the >answer but i want to be sure) > >-------- >egtb >adaptive 750K 24M 192M 24M 48M >cache=512M That looks excessive unless you have a huge amount of RAM.
