WebWhen solving the graph coloring problem with a mathematical optimization solver, to avoid some symmetry in the solution space, it is recommended to add the following … WebGiven an undirected graph, a graph coloring is an assignment of labels traditionally called "colors" to each vertex. A graph coloring must have a special property: given two adjacent vertices, i.e., such that there exists an edge between them, they must not share the same color. The origin of the problem comes from the problem of coloring a map ...
