We present computational results with a heuristic algorithm for the parallel machines total weighted tardiness problem. The algorithm combines generalized pairwise interchange neighborhoods, dynasearch optimization and a new machine‐based neighborhood whose size is non‐polynomial in the number of machines. The computational results significantly improve over the current state of the art for this problem.
