A (2 + ε)-approximation algorithm for the generalized preemptive open shop problem with minsum objective
Abstract
In this paper we consider a generalized version of the classical preemptive open shop problem with sum of weighted job completion times objective. The main result is a (2 + ε)-approximation algorithm for this problem. In the last section we also discuss the possibility of improving our algorithm. © 2002 Elsevier Science (USA).
