SNormFunction

public enum SNormFunction

Describes a S-norm (T-conorm) function, usually used for forming a union of fuzzy sets.

A function S must satisfy the following axioms in order to be S-normed (T-conormed):

1. Boundary condition: S(1, 1) = 1, S(1, 0) = 1, S(0, 1) = 1, S(0, 0) = 0
2. Commutativity: S(a, b) = S(b, a)
3. Monotonic: If a <= a' and b <= b' Then S(a, b) <= S(a', b')
4. Associativity: S(T(a, b), c) = S(a, T(b, c))
