Also i can make my functions more specific. instead of a general code in my program i can make it of course for black and white. in such ways for such simple tests you can beat anything. 2 million legal moves a second at depth-1 then times about 40 and factor 2 slowdown becuase of pinned piece reduction. that makes about 40 million nps a second for perft. Movei is at about 20MLN a second. >On December 31, 2002 at 12:36:32, Vincent Diepeveen wrote: > >>hi, >> >>crafty is doing perft with 32 bits signed counting: >> >>Celes (Johan Hutting): perft(7) >>Celes (Johan Hutting): goh >>Celes (Johan Hutting): total moves=-1099065436 time=792.39 > > >I suggest that you download movei00_799 >It has not this problem. >I am interested if diep can beat it in calculating perft. > >You can download movei in the following link when you click download >http://wbec-ridderkerk.nl/ > >You can use it as a winboard engine to calculate perft click alt 1 to send >winboard a command that you want. > >In the beginning of the game it may give you perft 7. >If you want to calculate perft from a different position you can give it the >position by file->paste position from clipboard and later calculate perft and it >works for every position except positions when en passent is legal. > >for calculating perft in position when en passent is legal setup the position >one ply earlier,go to edit game mode and do the move and then click >alt 1. > >Note that I have a special program that calculates perft even faster >that you download together with movei but this program cannot play and original >movei is fast enough to beat every thing that I know in perft. > >Interesting to know if it also can beat Diep in the perft game. > >Uri
