The Discounted {0-1} Knapsack Problem (D{0-1}KP) is an extension of the classical 0-1 knapsack problem (0-1 KP) that consists of selecting a set of item groups where each group includes three items and at most one of the three items can be selected. The D{0-1}KP is more challenging than the 0-1 KP because four choices of items in an item group diversify the selection of the items. In this paper, we...
Traditional threshold image segmentation method is a time consuming problem, we aim to find an effective optimal tool for proper threshold segmentation methods (e.g. Otsu and Kapur). In this work, we present a learning strategy based particle swarm optimization algorithm with an exchange method (LPSOWE). First, for enhancing the exploration ability and maintaining the convergence rate of the traditional...
