Abstract

Previous researches have shown the success of using Reinforcement Learning in solving combinatorial optimization problems. The main idea of these methods is to learn (near) optimal evaluation functions to improve local searches and find (near) optimal solutions. STAGE algorithm, introduced by Boyan & Moore, is one of the most important algorithms in this area. In this paper, we focus on Bin-Packing problem, an important NP-Complete problem. We analyze cost surface structure of this problem and investigate "big valley" structure for the set of its local minima. The result gives reasons for STAGE's success in solving this problem. Then by comparing the results of experiments on Bin-Packing problem, we analyze the effectiveness of steepest-descent hill climbing, stochastic hill climbing and first-improvement hill climbing as the local search algorithms in STAGE.
