GRAPH COLORING AND ITS APPLICATIONS

WebFeb 20, 2024 · Graph coloring refers to the problem of coloring vertices of a graph in such a way that no two adjacent vertices have the same color. This is also called the vertex coloring problem. If coloring is done using at most k colors, it is called k-coloring. The smallest number of colors required for coloring graph is called its chromatic number.
