Scheduling on Unrelated Parallel Machines

  • Vijay V. Vazirani

Abstract

LP-rounding has yielded approximation algorithms for a large number of NP-hard problems in scheduling theory (see Section 17.6). As an illustrative example, we present a factor 2 algorithm for the problem of scheduling on unrelated parallel machines. We will apply the technique of parametric pruning, introduced in Chapter 5, together with LP-rounding, to obtain the algorithm.
