Regarding the recent posting by Ozan Yigit on Chess 0.5: If these are the same as the 0.5 sources that appeared in two old version of Byte magazine, then I may be able so save you a lot of work. In particular I once typed these entire sources in (with comments) and did a pascal --> 4.2 C conversion. Both versions were run a lot, but there seems to be some insipid bugs from the original source (minor ones -- usually due to lack of knowledge). I also interfaced it to the Ritchie move generator and a hashed data base lookup table (some one else wrote part of this code). Since then my interests have changed... I am willing to share these with other peole, but have absolutely no time for either: [1] filling lots of mail/news requests nor [2] getting all the appropriate licensing agreements signed. as i am trying to work on a thesis. I also have no good way of getting mail to Ozan Yigit. If he or someone else can find a mail path to me, or somehow contact me (see below) AND get the licensing arrangements completed, I would be more than happy to share this with the net. - mike ps: The C version ran MUCH better than the pascal version in speed. It is also changed in some small bell and whistle type ways as well as 'optimized C' code (and 1 assembly language routine 'nxtts') for the bit manipulation routines.

I had heard about someone doing a C conversion in Caltech, but could not really find out that it was you. You would indeed same me some work, and probably make eveyone on the net very happy. > > I am willing to share these with other peole, but have >absolutely no time for either: > [1] filling lots of mail/news requests > nor > [2] getting all the appropriate licensing agreements signed.

He is expecting it :-) The Pascal sources, and its C derivative, in accordance with the copyright laws, will contain copyright date, and the names of its authors, and a note specifiying that the sources may only be used for non-commercial purposes. oz [the quote for tonite: you do not always get the rook you want, but sometimes, you get the knight you need :-)] -- The best way to have a Usenet: [decvax|ihnp4]!utzoo!yetti!oz good idea is to have a Bitnet: oz@[yusol|yuyetti].BITNET lot of ideas.
