What degrees can a … WebBipartite graphs with at least one edge have chromatic number 2, since the two parts are each independent sets and can be colored with a single color. Conversely, if a graph can be 2-colored, it is bipartite, since all edges connect vertices of different colors. This means it is easy to identify bipartite graphs: Color any vertex with color 1 ... Web1 Answer. Sorted by: 3. An edge e = u v is a bridge in G if there is no path between u and v in G − e. In general, u and v are cut vertices, but there are some special cases you must treat with care.

WebJun 21, 2024 · The algorithm bears the name of two American scientists: Richard Bellman and Lester Ford. Ford actually invented this algorithm in 1956 during the study of another mathematical problem, which eventually reduced to a subproblem of finding the shortest paths in the graph, and Ford gave an outline of the algorithm to solve this problem. WebJun 11, 2024 · Use your efficient algorithm n times (once per instance) to find a HP in each of them, if it exists. If there is a HP in any of these n graphs, and it can be converted to a HC by adding the particular vertex that was deleted in that graph, then you have found a HC -- and if there isn't, there can't be any HC. – j_random_hacker.
