Automata and Computability - An undirected graph is bipartite if its nodes may divided into two sets so that all edges go from a node in one set to a node in the other set. Show that a graph is bipartite if and only if it doesn’ ...
Topological Sorting - An algorithm for computing a topological ordering of a DAG (Directed Acyclic Graph) repeatedly finds a node with no incoming edges and deletes it. This will eventually produce a topological ordering, ...
