WebApr 5, 2024 · This concept is known as "cardinality," which is a way of measuring the size of infinite sets. Two sets are said to have the same cardinality if there exists a one-to-one correspondence between the elements of the two sets. In other words, if we can match each element in set A with a unique element in set B, and vice versa, then the sets have ... WebMaximum cardinality matching is a fundamental problem in graph theory.
