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.
