Task 2: This task will have you verifying a certificate to the Vertex Cover problem. A Vertex Cover is a subset of vertices, cina graph, such that every edge in the graph has at least one of its end points in c. The decision version of the Problem is: Dees G have a vertex cover of size K? Write a python program that takes a graph G. a number and a possible certificate to this problem / Your program returns True, if I is a vertex cover of size k in the graph G and False otherwise, The graph is given in a file textGraph.txt. A file named vertexcover.txt is also given which contains a group of possible vertex cover sets. For this question you can assume k = 4. Figure 2: Graph G For example: Your program might do the following: Enter the filename for graph: textGraph.txt Enter the filename for clique vertexcover.txt 11,3,4,5) Yes 2.4.5.6: No 3.4 : No 13.4.2) : No (3,4,5,2 No PAL A File named vertexcover.txt is also given which X.COM For this out.
