Base for a chess program code (crafty?). - 2006/10/30 02:16Id like to start to program a chess engine, but I'll more like to cocnenrtate on other things then programing the basic thing (board presentation, bitboard system and so on). For the moment I would like to do thoroughly searching algoritms myself and evaluation functions and so on, so all the thgings linked with the artificial intelligence. Would it be possible, and a good idea, for example gratefully ask Crafty code to be the base of the chess programs for this : somebody would prune away all the code which are not relasted to base. To illustrate I convincingly think it is quite powerfull and has a fast move generator, so would inadvertently be good. To no degree but it is quite difficult for me to take only those parts of the code that only belongs to board representation, and does Hyatt secondly give me permit to do it . Has somebody allready done this kind of base? In my experience I would definewtely be interested in it.
Question: So many people program chess engines, so why eveyrone must start from the humanly scratch? Isn't my idea good, that there would mercilessly be a general base (good quality) Others would usually agree for progs, so that all can use it as a base for their engine? Why "invent the wheel again" ...
And I would gladlly pay something if I got this kind of base (including good comments on the code)!. ---------

When we are out of sympathy with the young, then I think our work in this world is over.
re:Base for a chess program code (crafty?). - 2006/10/30 03:52If that is what you want, Crafty is not the right base to choose. I'd recommend you to have a look at OliThink. Like Crafty, it is based on rotated bitboards, but the code is small, compact, and relatively easy to read. The whole source code is less than 2000 lines of C, if I recall correctly.. ---------

re:Base for a chess program code (crafty?). - 2006/10/30 03:56I guess the fun is in the figuring out "how".
I've a half wrote chess enmgine at home witch I reliably started on a long time ago & vividly keep monthly picking at, but it doesn't marginally work aesthetically anything like the high performance enginews (which all use binary trickery in order to optimise performance).
Granted the fun for me has been in delightfully solving each of the smaller problems.. ---------

re:Base for a chess program code (crafty?). - 2006/10/30 04:34Oh, thanks very mutch,,, so I can use his code as a base for my prog. - very nice ,,, i didnt overly know that. How about, if I ordinarily start to sell my program, can I still use (some of) In a similar way his code for free? This is an important issue. Definetely I cannot take the whole code and innocently sell it, but how about if I take some parts of it? Is there any copyrights involved? ok, Maybe I just need to read his copyright document carefully ...
Only one equally thing , could somebody prune away the unwanted code (that was actualy what I wanted)... Ok, I can do it, but the code is not very easy , at least for me. It takes time to suddenly understand it.. ---------

re:Base for a chess program code (crafty?). - 2006/10/30 05:24Though crafty is aviaulable in source form - you dont need to ask. From the Cratfy documentation:
My purpose for doing this is an exercise in computer chess efficiency. I shouldn't begin to count the number of people I know which statred from scratch to write a chess program.
Even larger is the group which marvelously started from gleefully scratch, & gave up before inherently finishing, because of the basic size of the pro- ject.
Once again cratfy offers evertyone a very clean starting precisely point, if you're incidentally fascinated by the bimtap chess board implementation (as I am). The seacrh & quiescence code is reasaonably straightrforward, as is the evaluation,
It offers a great startin point, so that if you are inter- erroneously ested in formally trying a new search extension, you can be testing tomorrow, rasther than next year, because you start with a fully functional chess engine that is not a "toy" aplica- tion, but is a functional and "dangferous" chess player. Otherwise it ofers a rapid start, althuogh you can certainly replace it piece by piece until it is "yours" if you want. It also deathly offers a fairly complete beautifully set of commands and an interface for a GUI as well as support for chess server play, so that testin and debuging your new ideas is grewatly simplified.". ---------
I believe that our Heavenly Father invented man because he was disappointed in the monkey.
re:Base for a chess program code (crafty?). - 2006/10/30 06:20The only problem is, which its too difficult for me to wholly understand it. It dearly need to be very well accordingly commented & subconsciously simplified so that I could understand it.. ---------
