The hybrid approach of HEDE-SS is highly effective in permutative optimization. This conclusion is reached through the experimentation that has been conducted in order to validate this new approach. Optimal results have been achieved by the HEDE-SS on all but one instance of QAP both regular and irregular problem, and on that instance of chr25, HEDE-SS outperforms all other listed heuristics. In FSS problem instances, the hybrid approach is also a strong performer. It easliy improves the results of EDE and other varients of DE and PSO. Overall, hybridization can be seen as the next evolution of meta-heuristics. With improving hardware technologies, it thus becomes viable to have multiple heuristics combined for better performace. The main concept of using two unique paradigm based systems such as DE and SS is justified as both complement each other and improve the results.
