Greedy sat algorithm
Webα, an algorithm A is an α-approximation algorithm for a given minimization problem Π if its solution is at most α times the optimum, considering all the possible instances of problem Π. The focus of this chapter is on the design of approximation algorithms for NP-hard optimization problems. We will show how standard algorithm de- WebGREEDY ALGORITHMS FOR THE MAXIMUM SATISFIABILITY PROBLEM: SIMPLE ALGORITHMSAND INAPPROXIMABILITY BOUNDS∗ MATTHIAS POLOCZEK†, GEORG SCHNITGER‡, DAVID P.
