Since back edges are those edges ( u, v) connecting a vertex u to an ancestor v in a depth-first tree, so no back edges means there are only tree edges, so there is no cycle. So we can simply run DFS. If find a back edge, there is a cycle.

WebSolved by verified expert. To prove that the 3-colorable problem ≤P is the 4-colorable problem, we need to show that given an instance of the 3-colorable problem, we can construct an instance of the 4-colorable problem such that the two instances are equivalent. Let G = (V, E) be an undirected graph that we want to determine if it is 3-colorable.
