Graph Coloring and Chromatic Numbers - Brilliant

In 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 the vertices of a graph such that no two adjacent vertices are of the same color; this is called a vertex coloring. Similarly, an edge coloring assigns a color to each edge so tha… WebIn the depth-first search (DFS) algorithm, firstly we traverse from the starting node of the graph G’, from there we extend our traversing down till we discover the desired node or the last node which is not having any child nodes to traverse. From the desired node the algorithm starts backtracking towards the latest node that is yet to be traversed.
