Graph theory map coloring
WebSolution: In the above cycle graph, there are 3 different colors for three vertices, and none of the adjacent vertices are colored with the same color. In this graph, the number of vertices is odd. So. Chromatic number = 3. Example 2: In the following graph, we have to determine the chromatic number. WebNov 1, 2024 · If a graph is properly colored, the vertices that are assigned a particular color form an independent set. Given a graph \(G\) it is easy to find a proper coloring: give …
