Abstract

We study the minimum total weighted completion time problem on parallel machines, which is known to be strongly $\mathcal{NP}$-hard. We develop general ideas leading to exponential neighborhoods in which the best improving neighbor can be determined by calculating a maximum weighted matching of an improvement graph. In a second step we introduce neighborhoods that form the base for the exponential neighborhoods.
