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. WebA bidirected graph may be regarded as an orientation of a signed graph, similarly to how a directed graph may be viewed as an orientation of an ordinary undirected graph. Other meanings. A symmetric directed graph (that is, a directed graph in which the reverse of every edge is also an edge) is sometimes also called a "bidirected graph". dwayne rice obituary
