WebFeb 20, 2014 · 3 Answers. You are correct that this is a graph coloring problem. Specifically, you need to determine if the graph is 2-colorable. This is trivial: do a DFS on the graph, coloring alternating black and white nodes. If you find a conflict, then the graph is not 2-colorable, and the scheduling is impossible.

C Program to implement Graph Coloring using Backtracking

WebIntroduction. To study graphs as mathematical structures, we use graph labeling. Graph labeling is a way of assigning labels to vertices, edges, or faces of a graph. It can be done in various ways. Graph coloring is one of the prime methods of labeling. It is a process of assigning labels or "colors" to elements of a graph following certain constraints. WebJun 9, 2015 · In general, graph coloring refers to the problem of finding the minimum number of colors that can be used to color the nodes of a graph, such that no two adjacent (connected) nodes have the same color. For example, the graph in Figure 2 can be colored with two colors (green and yellow). Figure 2: This simple graph coloring requires two …

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. WebProblem - Bipartite Graph using DFS I have explained the solution in the best possible way!
