jFuzzyLogic Features

    - Implements Fuzzy control language (FCL) IEC-61131-7 specification.
    - Parametric optimization algorithms.
    - Membership functions:
        -Continuous: GenBell, Sigmoidal, Trapetzoidal, Gaussian, PieceWiseLinear, Triangular, Cosing, Dsigm
        -Discrete: Singleton, GenericSingleton
        -Custom membership functions can be defined
    - Defuzzifiers:
        -Continuous: CenterOfGravity, RightMostMax, CenterOfArea, LeftMostMax, MeanMax
        -Discrete: CenterOfGravitySingletons
        -Custom defuzzifiers can be easly created
        -Function based deffuzifiers (e.g. "TERM drainage := FUNCTION (-2 * pressure * Ln(pressure)) + (temp * 4);");
    - Rule aggregation (how rules are aggregated / accumulated): BoundedSum, Max, ProbOr, Sum, NormedSum
    - Rule connection operators (AND, OR): Max / Min, ProbOr / Prod, BoundedDif //BoundedSum, etc.
    - Rule implication methods (activation): Min , Product.
