The problem is to find if it is possible to assign nodes with m different colors, such that no two adjacent vertices of the graph are of the same colors. If the solution exists, then display which color is assigned on which vertex. Starting from vertex 0, we will try to assign colors one by one to different nodes.

In this problem, each node is colored into some colors. But coloring has some constraints. We cannot use the same color for any adjacent vertices. For solving this problem, we need to use the greedy algorithm, but it …
WebGraph Coloring Problem. Graph coloring (also called vertex coloring) is a way of coloring a graph’s vertices such that no two adjacent vertices share the same color. … WebFor example, if you are solving a graph coloring problem, you can use a variable that stores the index of the last vertex that caused a color clash with the current choice, and a function that ...
