Coloring Number Graph. Graph coloring by CSP (CONSTRAINT SATISFACTION PROBLEMS) algorithms from Russell And Norvig's Genetic algorithm approach to Karp's chromatic number (graph coloring) problem. Chromatic Number is the minimum number of colors required to properly color any graph.
Given a graph with n vertices. Graph Coloring Algorithm Chromatic Number: The smallest number of colors needed to color a graph G is called its chromatic number. Graph Coloring is a way of coloring the vertices of a undirected graph such that no two adjacent vertices share the same color.
A graph coloring is distinct from a graph labeling in that in the former, the same label may be used more than once.
For instance, if you need the color number.
This interesting interview problem was asked by Google. In its simplest form, it is a way of coloring the vertices of a graph such that no two adjacent vertices are of the same color. This class performs randomized testing for The chromatic number is the minimal number of colors needed to color the vertices of the graph.
