Released Toledo Nanochess with Winboard interface

Hi everybody, I have uploaded a new version of Toledo Nanochess and it is 40% faster. Also a version with integrated Winboard interface, the source and the optimized executables are downloadable as a pack. The source code sizes up at slightly less than 2 KB of C language. This is currently the small...

Re: mate distance pruning

On the latest version of Toledo Nanochess the mate pruning is done as a very high score 131072 points minus depth multiplied by 1024, this does a nice effect of doing fast mate, although it doesn't help playing strength. On an early version of my IOCCC entry (circa 2005, still available from the IOC...

Re: Current world's smallest chess program

I was talking about PGN of this match. Also, could someone point me to the nunn.pgn file? I tried a Nunn match between micro-Max 1.6 and Toledo_nanochess. (Yes, the protocol of this new Toledo does support force mode, so you can play it with an external book!) To make for approximately fair CPU time...

By the way, if someone wants to put Toledo Nanochess in a tournament, please tell me first, so I can be aware of it.

Re: Current world's smallest chess program

Very interesting, I hope you could run a Nunn match between factory-default Toledo Nanochess and factory-default Micromax v1.6.

Re: Current world's smallest chess program

I did the following measurements: 1. byte-size, using *NIX end-of-line \n (not \r\n) 2. Non-blank: Characters !isspace(c) 3. IOCCC: Characters !isspace(c) minus { } ; followed by isspace In case of doubt use byte-size. For Bill: To see the Javascript source, download the compressed file and open it ...

Current world's smallest chess program

It contains my four winning entries from the IOCCC, and three previously-unreleased chess programs: Toledo Nanochess, a chess program in C that occupies only 1274 non-blank characters, still being smaller, it beats Mic...
