Re: Need help to make Crafty work

cores=1 is illegal so far as Crafty is concerned. cores=0 says to disable the SMP thread stuff completely. If it accepted cores=1 it would incur some overhead that gains nothing useful at all. Has always been that way. The ideal solution would probably be to parse the cores command and if it is <= 1...

Re: Need help to make Crafty work

Yes, this was on my mac. But the way Crafty handles input is quite serial. IE a chunk of text is read, and everything up to the first new line character (or ; if I remember correctly) is executed. Then the next segment of the input, again up to the new line or ; is read and executed. I don't see any...

Re: Need help to make Crafty work

For the record, after I type "go" and wait a couple of seconds and type "force" crafty stops the search instantly. It will probably announce a move, but since you put it into force mode, you probably have something else in mind anyway. Winboard protocol is quite simple. Which means it has a few ambi...

Re: Need help to make Crafty work

something wrong here. (1) Crafty ALWAYS sends "feature reuse=0". Just checked the source. (2) Crafty NEVER executes commands out of sequence. It reads and executes them one at a time, in the order they are entered. Are you running a standard Crafty 25.2 version (last released version by me) or are y...

Re: WCCC vs TCEC Chess Engine Competitions..

Way past time to get off the old anti-ACM bandwagon, Way past time to get off the old ICGA bandwagon also unless they reinvent themselves. Pretty sad comment. The main thrust of the ICCA (then ICGA) was to foster interest in computer chess. They STILL provide that service via the annual mind games ...

Re: WCCC vs TCEC Chess Engine Competitions..

I hardly missed an ACM event, which started in 1970. I didn't compete until 1976, as we had no interactive terminal access on our computers at USM until we bought our Xerox Sigma 9. The very early events were VERY "dicey" to be kind. I remember things like pawns on the 8th rank, programs that got hu...

Re: WCCC vs TCEC Chess Engine Competitions..

If I had to post one complaint about the ICGA (ICCA at the time) it would be that they catered too much to the commercial programs/programmers. One example: Ken Thompson and I proposed, in the late 70's, that the ACM/ICCA tournaments should move to an automatic interface mode. There were several rea...

Re: WCCC vs TCEC Chess Engine Competitions..

I would like to add something here, since "some" are trying to keep various types of "bitterness" alive and well. Computer chess went through three really distinct phases. Phase 1 started in 1970 and continued into the early 90's, where we had annual ACM computer chess tournaments (and every three y...

Re: max number of pseudo legal move

A LONG time ago, I decided to make this particular question a non issue. I use a big array (vector). I have another vector last[ply]. The idea is then that for all plies, last[ply] points one past the last move for the current ply. If you want to iterate over the complete move list for ply=4, you do...
