Abstract
This paper presents a hybrid discrete differential evolution (HDDE) algorithm to solve the Pm//
problem. The coding and decoding scheme based on job permutation is applied in the algorithm. The algorithm employs several efficient heuristics in the initialisation phase and incorporates an insertion-based local search. To validate the proposed algorithm, computational experiments are conducted on a benchmark problem set from the literature. Computational results show that the HDDE algorithm outperforms the existing state-of-the-art algorithms for the Pm//
problem.
