Title: Proposal of Adjustment Type Genetic Algorithm for Knapsack Problem
Abstract: The greedy algorithm is one of solution methods for knapsack problem. Although this algorithm does not necessarily obtain the optimal solution, it can obtain a good solution in short time. We consider this algorithm is very effective at judging the importance of each item.In this paper, we propose a new genetic algorithm for solving a knapsack problem. The algorithm can adjust a search area in consideration of the stability of each item which can obtain from the greedy algorithm. Moreover, we apply the proposed method to a multi-objective problem and a large-scale problem, and test the effectiveness.
