*** Typo in problem 3. Where it says "what is the largest vertex-cover" it should say, "what is the smallest vertex-cover" ***

Problem 2. Consider the CNF below where means complement of ri 2. where means of Convert this CNF into a graph G (V, E) so that G has a clique of size 4 if and if the CNF is satisfiable. Does G have a clique of size Problem 3. For the graph G (VE) above construct the complement graph G (V, E). What is the largest clique in G? what is the largest vertex-cover in G
