Hybrid symbiotic organisms search algorithm for solving 0-1 knapsack problem

We propose a new binary version of hybrid symbiotic organisms search algorithm based on harmony search with greedy strategy for solving 0-1 knapsack problems. A greedy strategy is employed to repair the infeasible solution and optimise the feasible solution. The experiments are carried out in small-scale and large-scale knapsack problem instances. We report on computational experiments which are compared with the results achieved with other state-of-the-art approaches. The results attest the performance of our approach.
