1. (Schöning 36, adapted) Let F be a clause set with the atomic formulas A₁,..., An, where each clause contains at most two literals (such clauses are called Krom clauses). How large can Res* (F) be at most? Use this to give an efficient algorithm for determining satisfiability of Krom formulas and analyze its complexity.
