Graph coloring using backtracking example

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. WebApr 15, 2013 · I am working an m_coloring problem wherein I have to determine the chromatic number m of an undirected graph using backtracking. The (java) solution I have thus far is increment m, try the m_Coloring method, and then repeat if a solution is not found. However, for the larger files, if m is over 6, the computation takes forever.
