WebAug 27, 2024 · A Graph is a collection of nodes (or vertices), connected by edges (or not). Nodes directly connected by edges are called neighbours. In our representation of graphs, nodes are numbered and edges are represented by the two node numbers connected by the edge separated by a dash. WebIn this algorithm Step-1.2 (Continue) and Step-2 (backtracking) is causing the program to try different color option. Continue – try a different color for current vertex. Backtrack – try a different color for last colored vertex. …

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. WebThe convention of using colors originates from coloring the countries of a map, where each face is literally colored. This was generalized to coloring the faces of a graph embedded in the plane.
