Method Detail

and

public final IFuzzySet<T> and(IFuzzySet<T> a,
                              IFuzzySet<T> b)

Description copied from interface: IFuzzySets

Performs a fuzzy logic and between this fuzzy set and the given one

Specified by:

and in interface IFuzzySets<T>

Returns:

the fuzzy set resulting from the and between this fuzzy set and the given one.

compose

public final IFuzzyRelationship compose(IFuzzyRelationship relA,
                                        IFuzzyRelationship relB)

Description copied from interface: IFuzzySets

Performs composition between fuzzy relationships. This method is generally used when it is necessary to evaluate a rule (which can be tought as a relationship) on the basis of a fuzzified input.

Specified by:

compose in interface IFuzzySets<T>

Returns:

the relationship resulting from the composition.

intersect

public final IFuzzySet<T> intersect(IFuzzySet<T> a,
                                    IFuzzySet<T> b)

Description copied from interface: IFuzzySets

Performs the fuzzy intersection between this fuzzy set and the given one. Intersection is usually performed using a T-Norm. Remember that in fuzzy terms, the intersection between A and its fuzzy complement can be different from the empty set.

Specified by:

intersect in interface IFuzzySets<T>

Returns:

the fuzzy set resulting from the intersection between this fuzzy set and anotherSet

or

public final IFuzzySet<T> or(IFuzzySet<T> a,
                             IFuzzySet<T> b)

Description copied from interface: IFuzzySets

Performs a fuzzy logic or between this fuzzy set and the given one

Specified by:

or in interface IFuzzySets<T>

Returns:

the fuzzy set resulting from the or between this fuzzy set and the given one.

union

public final IFuzzySet<T> union(IFuzzySet<T> a,
                                IFuzzySet<T> b)

Description copied from interface: IFuzzySets

Performs the fuzzy union between this fuzzy set and the given one. Union is usually performed using a T-Conorm. Remember that in fuzzy terms, the union between A and its fuzzy complement can be different from the Universe.

Specified by:

union in interface IFuzzySets<T>

Returns:

the fuzzy set resulting from the intersection between this fuzzy set and anotherSet.
