Abstract

Based on the work by Congram, Potts and Van de Velde, we develop for the single-machine total weighted tardiness scheduling problem an enhanced dynasearch neighborhood obtained by the generalized pairwise interchange (GPI) operators. Despite of the wider neighborhood considered, a fast search procedure using also elimination criteria is developed. The computational results significantly improve over those of Congram, Potts and Van de Velde.
