Graph colouring in daa
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. WebIn graph theory, graph coloring is a special case of graph labeling; it is an assignment of labels traditionally called "colors" to elements of a graph subject to certain constraints. In its simplest form, it is a way of coloring …

WebChromatic Number of some common types of graphs are as follows-. 1. Cycle Graph-. A simple graph of ‘n’ vertices (n>=3) and ‘n’ edges forming a cycle of length ‘n’ is called as a cycle graph. In a cycle graph, all the vertices are of degree 2. Chromatic Number. If number of vertices in cycle graph is even, then its chromatic number = 2.
