About Mizar

Mizar is my chess engine. Actually it is very weak, but it is bug free (I hope!;-)). I write chess engines for hobby (i am an engineer-architect) and i don't think that Mizar will become very strong. So i want a free chess engine that is nice to play against.

If you want suggest feature to implement contact me; actually i'd like to add:

Personality evaluation (you can modify every bonus in eval in option.ini...i'd like to have different set of values)
Difficult level (ELO based)

I'd like to say thank to Dann Corbit: his incredible work was (is) very useful for me.

Technical consideration [release 3.0]

After a 'bugs fix only release' i've added some improvement to Mizar: static pruning, aspiration search and ponder. I've also rewritten some parts of evaluation and tuned parameters. I've also fixed little bugs and did some changes to have more compatibility with EPD2WB (thanks to Dann Corbit). About static pruning i've used a form of "Futility" and "Extend Futility Pruning" and an idea of Don Dailey. See Readme.txt ('Inside Mizar' section) and source code for detail. Some people mail me to ask to translate comments from italian to english: from now new comments will be in english (well...italish!;-)) and little by little i hope to translate others. And now? Well it's dynamic pruning time...
