A **pseudometric space** is a generalization of a metric space. In a metric space, the distance between two points must satisfy certain properties, including the identity of indiscernibles, which states that the distance between two distinct points must be positive. However, a pseudometric space relaxes this requirement. Formally, a pseudometric space is defined as a pair \\((X, d)\\), where: - \\(X\\) is a set.
