i'm studying np class , 1 of slides mentions: it seems verifying not present more difficult verifying present. ______ _________ hence, clique (complement) , subsetsum (complement) not members of np. was ever proved, whether complement of clique element of np? also, have proof? this open problem, actually! complexity class co-np consists of complements of problems in np . it's unknown whether np = co-np right now, , many people suspect answer no. just clique np -complete, complement of clique co-np -complete. (more generally, complement of np -complete problem co-np -complete). there's theorem if co-np -complete problem in np , co-np = np ,which huge theoretical breakthrough. if you're interested in learning more this, check out the wikipedia article on co-np , around online more resources.
