Crisp Set
A Crisp Set is a collection of distinct objects or elements that have a clear membership criterion. In this type of set, each element either belongs to the set or does not, with no ambiguity. For example, in a set of even numbers, the number 2 is a member, while the number 3 is not.
Crisp sets are foundational in classical set theory and are often contrasted with fuzzy sets, where elements can have varying degrees of membership. This clear distinction makes crisp sets useful in various fields, including mathematics, computer science, and logic, where precise categorization is essential.
