Özet

The Chernobyl Disaster Optimizer (CDO) has recently been introduced metaheuristic algorithm inspired by the explosion in the 4th reactor of the Chernobyl nuclear power plant in 1986. Although the original CDO demonstrates excellent performance in solving continuous problems, it cannot be applied directly to the binary problems such as the 0-1 knapsack problem. The 0-1 Knapsack problem (0-1 KP) is one of the well-known NP-hard combinatorial optimization problem that is a challenging problem to solve efficiently using conventional techniques. The objective of this problem is to identify the optimal subset of items from a given set, with its own specific profit and weight, that maximizes profit while remaining within the capacity of the knapsack. Different methods have been proposed to solve the 0-1 knapsack problem. In this paper, the binary CDO algorithm is proposed to solve the 0-1 Knapsack problems and called as BCDO. Original CDO is adapted to 0-1 KP using S shaped transfer function. Several experiments were performed to compare the performance of the BCDO to several competing optimizers when solving 25 benchmark knapsack instances with different dimensions. The experimental results show the superiority of the proposed binary CDO algorithm.
