Abstract

For many NP-hard problems, achieving certain reasonable approximation ratios is no easier than computing optimal solutions. In other words, approximation is NP-hard. The negative results have fed an increased interest in approximation algorithms. The negative results of NP-hard problems such as MAX-CLIQUE, CHROMATIC NUMBER, MAX-3SAT, SET-COVER, and MAX-SNP are described. Some approximation algorithms that were recently discovered are presented.
