Anybody know of any good fuzzy logic libraries that I can use in my project? Functionality should allow things like fuzzy expert systems, use of logic operators etc... FFLL on sourceforge looked promising but they don''t allow combination of member functions using logic operators, so I was wondering if anybody knew another more complete library?

Explain.

The solution may be a combination of libraries (e.g. FFLL+something) instead of one single library.

My project involves fuzzy subsumption and command fusion, there are two modules, each uses a set of rules to generate its member function (one function defines directions where a robot can't go because of obstacles, and another where the robot would like to go to reach its goal) then one function is "subtracted" so to speak from the other to obtain a function that defines optimal directions for the robot. (Im not sure which logic operation that is). However FFLL will only let me go up to the generation of the initial two member functions, it can't do combinations.

*bump* anyone?

Uhmmm, I wrote a class for a fuzzy bool in half an hour (maybe, I can''t say exactly because I was doing other things at the time so I was on and off). It''s not exactly difficult to do, you just have to make some decisions about certain things along the way (for example, probabilistic or minimum version of the and operator). Try writing it yourself and expanding because it''s such a simple thing.

this is a good free lib.

That is a good idea (I have them and love them), but 4the huge price tags can be really restrictive... One otehr place to look would be http://www.generation5.org/ (NOT A CLICKY!) if you don''t want to write your own.
