摘要

In this paper, we propose a distributed algorithm to solve the bi-objective shortest path (BOSP) problem. The proposed algorithm can obtain all the Pareto optimal solutions for such a multi-objective combination optimization problem. Moreover, rapid comparison and pruning techniques are designed to alleviate the space/message complexity burden common in multi-objective optimization problems. Simulation results show the validity of the proposed algorithm, as well as rapid comparison and pruning techniques.
