A new DSATUR-based algorithm for exact vertex coloring
This paper describes a new exact algorithm PASS for the vértex coloring problem based on the well Keywordsknown DSATUR algorithm. At each step DSATUR maximizes saturation degree to select a new candidate Color vértex to color, breaking ties by máximum degree w.r.t. uncolored vértices. Later Sewell introduced a Graph new tiebreaking strategy, which evaluated available colors for each vértex expl...
متن کاملAn exact DSatur-based algorithm for the Equitable Coloring Problem
This paper describes an exact algorithm for the Equitable Coloring Problem, based on the well known DSatur algorithm for the classic Coloring Problem with new pruning rules specifically derived from the equity constraint. Computational experiences show that our algorithm is competitive with those known in literature.
متن کاملA DSATUR-based algorithm for the Equitable Coloring Problem
This paper describes a new exact algorithm for the Equitable Coloring Problem, a coloring problem where the sizes of two arbitrary color classes differ in at most one unit. Based on the well known DSatur algorithm for the classic Coloring Problem, a pruning criterion arising from equity constraints is proposed and analyzed. The good performance of the algorithm is shown through computational ex...
متن کاملAn Improved DSATUR-Based Branch-and-Bound Algorithm for the Vertex Coloring Problem
Given an undirected graph, the Vertex Coloring Problem (VCP) consists of assigning a color to each vertex of the graph in such a way that two adjacent vertices do not share the same color and the total number of colors is minimized. DSATUR-based Branch-and-Bound algorithm (DSATUR) is an effective exact algorithm for the VCP. One of its main drawback is that a lower bound is computed only once a...
متن کاملA new Simulated Annealing algorithm for the robust coloring problem
The Robust Coloring Problem (RCP) is a generalization of the well-known Graph Coloring Problem where we seek for a solution that remains valid when extra edges are added. The RCP is used in scheduling of events with possible last-minute changes and study frequency assignments of the electromagnetic spectrum. This problem has been proved as NP-hard and in instances larger than 30 vertices, meta-...
