WebThe pseudo-code for such an algorithm is: We know how to implement such an algorithm in Python. One such implementation is: def is_bipartite(g): """ Check if graph, g, is bipartite. Arguments: g -- undirected graph Returns: True if g is bipartite, False otherwise. WebIn graph theory, a vertex cover (sometimes node cover) of a graph is a set of vertices that includes at least one endpoint of every edge of the graph.. In computer science, the problem of finding a minimum vertex cover is a classical optimization problem.It is NP-hard, so it cannot be solved by a polynomial-time algorithm if P ≠ NP.Moreover, it is hard to …
