Tags Cardinality Discrete Discrete math Sets This proves that there is a one-to-one correspondence between (0,1) and (1,∞), and therefore, they have the same cardinality.In summary, the conversation discusses the concept of infinite sets having the same cardinality, using the example of a ...

In Discrete Mathematics, the set operations are performed on two or more sets. In a set theory, there are five major types of operations performed on sets, such as: Union of sets (∪), Intersection of sets (∩), Difference of sets ( – ), Complement of sets ('), and Symmetric diffe...
关键词: Computer Science - Discrete Mathematics 摘要: It is known that the maximum cardinality cut problem is NP-hard even in chordal graphs. In this paper, we consider the time complexity of the problem in proper interval graphs, a subclass of chordal graphs, and propose a dynamic ...

In Mathematics in Science and Engineering, 1980 a Scalar Cardinality When X is a finite set, the cardinality |A| of a fuzzy set A on X is defined as |A|=∑x∈XμA(x). |A| is sometimes called the power of A (see De Luca and Termini, 1972b). ||A|| = |A|/|X| is the...

In several applications the solutions of combinatorial optimization problems (COP) are required to satisfy an additional cardinality constraint, that is to contain a fixed number of elements. So far the family of (COP) with cardinality constraints has been little investigated. The present work tackles...
