WebMay 12, 2024 · Inclusion-Exclusion Principle In case of two sets In many problems, we must include contributions of more than one term in our answer. This results in the inclusion of the same term more than once; hence we use the inclusion-exclusion principle. Clearly, in set theory, the union of two sets A and B can be represented as : The inclusion exclusion principle forms the basis of algorithms for a number of NP-hard graph partitioning problems, such as graph coloring. A well known application of the principle is the construction of the chromatic polynomial of a graph. Bipartite graph perfect matchings See more In combinatorics, a branch of mathematics, the inclusion–exclusion principle is a counting technique which generalizes the familiar method of obtaining the number of elements in the union of two finite sets; symbolically … See more Counting integers As a simple example of the use of the principle of inclusion–exclusion, consider the question: How many integers … See more Given a family (repeats allowed) of subsets A1, A2, ..., An of a universal set S, the principle of inclusion–exclusion calculates the number of elements of S in none of these subsets. A generalization of this concept would calculate the number of elements of S which … See more The inclusion–exclusion principle is widely used and only a few of its applications can be mentioned here. Counting derangements A well-known application of the inclusion–exclusion principle is to the combinatorial … See more In its general formula, the principle of inclusion–exclusion states that for finite sets A1, …, An, one has the identity This can be … See more The situation that appears in the derangement example above occurs often enough to merit special attention. Namely, when the size of the intersection sets appearing in the formulas for the principle of inclusion–exclusion depend only on the number of sets in … See more In probability, for events A1, ..., An in a probability space $${\displaystyle (\Omega ,{\mathcal {F}},\mathbb {P} )}$$, the inclusion–exclusion principle becomes for n = 2 for n = 3 See more
