Web(3) Theorem 1 (Inclusion-Exclusion for indicator functions) 1A =(∅)= X J⊆P (−1) J 1 A⊇(J). (4) The proof is to use the distributive law of algebra. In this instance it says that Y p∈P 1Ac p = Y p∈P (1−1A p ) = X J⊆P Y p∈J (−1A p ) = X J⊆P (−1) J Y p∈J 1Ap. Web1 Principle of inclusion and exclusion Very often, we need to calculate the number of elements in the union of certain sets. Assuming that we know the sizes of these sets, and their mutual intersections, the principle of inclusion and exclusion allows us to do exactly that. Suppose that you have two setsA;B.

WebInclusion-Exclusion The nicest proof of the inclusion-exclusion formula that I have seen in an elementary textbook is in Discrete Mathematics, written by Melvin Hausner *, 1992.It uses the idea of characteristic function χ S for the set S: χ S (y)=1 if y is in S, and χ S (y)=0 if y is not in S. Suppose we are given n sets, A i, 1≤i≤n, each contained in some universal set U.

"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.
