WebGraph Terminology. Adjacency: A vertex is said to be adjacent to another vertex if there is an edge connecting them.Vertices 2 and 3 are not adjacent because there is no edge between them. Path: A sequence of edges that allows you to go from vertex A to vertex B is called a path. 0-1, 1-2 and 0-2 are paths from vertex 0 to vertex 2.; Directed Graph: A … WebColoring an undirected graph means, assigning a color to each node, so that any two nodes directly connected by an edge have different colors. The chromatic number of a graph is the minimum number of colors needed to color the graph. Graph coloring is NP-complete, so there is no polynomial-time algorithm; but we need to do it anyway, for …

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. WebNov 7, 2024 · Problem statement: Given an undirected graph E.
