just on my last message i'm looking for good links, books and tutorials on the topics that would be of help to me as begginer that is.

It was a long time ago, but the Prolog books I used were "Programming in Prolog" by Clocksin & Mellish, and "The Art of Prolog: Advanced Programming Techniques" by Sterling.

Are you using SWI-Prolog? If not, and you are looking for a Prolog interpreter for Windows, you can get it from http://www.swi-prolog.org/ . It also uses xpce. But you can, if you prefer, just edit using your favourite text editor and run the Prolog program from the command line.

There are a few Prolog tutorials on the net but I don't think they are as good as the books.

I don't know any sources of information on the other stuff you are looking for, such as fuzzy logic. But your project sounds very interesting. I wish you good luck.

By the way, just to add to my last reply, I don't think this forum is a good one for your kind of question. Computing.net seems to be focussed on small technical problems, whereas you want something more academic. I would recommend finding a specialist forum, such as the comp.lang.prolog and comp.ai.fuzzy Usenet newsgroups.
