C++ Program to Perform Edge Coloring of a Graph

WebMathmatically, a proper vertex coloring of an undirected graph G= (V,E) is a map c: V -> S such that c (u) != c (v) whenever there exists an edge (u,v) in G. The elements of set S are called the available colors. The problem is often to determine the minimum cardinality (the number of colors) of S for a given graph G or to ask whether it is ... 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. high street walshaw bury
