This is the project I am working on. Use it as is at your own risk.
DotFuzzy 2.0 is an open source stand-alone class library for fuzzy logic based upon and an extension of MicheleBertoli's work.
The library is built in C# and can therefore be used by all languages the .NET environment supports. Because of a clean natural Object Oriented approach the library is easy to use and implement. DotFuzzy is designed to be a flexible, robust and scalable.
DotFuzzy implements fuzzification, rules validation/evaluation and defuzzification. It is also possible to save and load projects in XML, whose tags are similar to Fuzzy Control Language.
LinguisticVariable water = new LinguisticVariable("Water");
water.MembershipFunctionCollection.Add(new MembershipFunction("Cold", 0, 0, 20, 40));
water.MembershipFunctionCollection.Add(new MembershipFunction("Tepid", 30, 50, 50, 70));
water.MembershipFunctionCollection.Add(new MembershipFunction("Hot", 50, 80, 100, 100));
LinguisticVariable power = new LinguisticVariable("Power");
power.MembershipFunctionCollection.Add(new MembershipFunction("Low", 0, 25, 25, 50));
power.MembershipFunctionCollection.Add(new MembershipFunction("High", 25, 50, 50, 75));
