Which of the following cannot be solved using polynomial time?(a) Linear Programming(b) Greatest common divisor(c) Maximum matching(d) None of the mentionedI had been asked this question in homework.This interesting question is from Problem Solvable in Polynomial Time in division Intractable Problems of Automata Theory |
Answer» RIGHT ANSWER is (d) None of the mentioned The best explanation: In graph theory, a matching or independent edge set in a graph G is a set of edges WITHOUT common vertices. Given a graph (V, E), a matchingM in G is a set of pairwise non adjacent edges i.e. no two edges share a common vertex. |
