Crisp Set

+A **crisp set** is a fundamental mathematical collection where each element either fully belongs or entirely does not. Membership is absolute, represented by a binary choice of "in" or "out," unlike a [Fuzzy Set](/wiki/Fuzzy_Set) where elements can have partial degrees of belonging. It forms the basis of traditional [Set Theory](/wiki/Set_Theory).
