Explanation : The most important open question in complexity
t heor y is whether the P = NP, which asks
whether polynomial time algorithms actually exist
for NP-complete and all NP problems (since a
problem “C” is in NP-complete, iff C is in NP and
every problem in NP is reducible to C in
polynomial time). In the given question it is given
that some polynomial time algorithm exists which
computes the largest clique problem in the given
graph which is known NP-complete problem.
Hence P = NP = NP-Complete.
