5. Given an undirected graph ( G=(V, E) ), a vertex cover is a subset of ( V ) so that every edge in ( E ) has at least

5. Given an undirected graph G = (V, E), a vertex cover is a subset of V so that every edge in E has at least one endpoint in the vertex cover. The problem of finding a minimum vertex cover is to find a vertex cover of the smallest possible size. Formulate this problem as an integer linear programming problem.
