WebJan 13, 2024 · We study the behavior of the Douglas–Rachford algorithm on the graph vertex-coloring problem. Given a graph and a number of colors, the goal is to find a coloring of the vertices so that all adjacent vertex pairs have different colors. In spite of the combinatorial nature of this problem, the Douglas–Rachford algorithm was recently … WebFeb 1, 2024 · The following are the related works of bio-inspired optimization algorithms for solving graph coloring problems. In 1999, Hong proposed to use GA to solve graph coloring .

Then, from the proper coloring, we can get the number of colors used for that coloring. For a graph G, label the vertices v1,v2,…,vn and for each vertex in order, color it with the lowest color available. Greedy coloring can be done in linear time, but ...
WebMar 13, 2024 · The Graph Coloring Problem We are given an undirected graph; a set of nodes and edges where each edge connects two nodes, and each node has a color. The problem is to find the coloring of the graph (the color assigned to each node) that: minimizes the number of distinct colors used, such that no two nodes connected by an …
