大规模多目标最优化的同伦方法

A Homotopy Method for Large-Scale Multi-Objective Optimization

Andreas Adelmann, Peter Arbenz, Andrew Foster, Yves Ineichen

摘要:

提出了一种求解多目标最优化问题的同伦方法,该方法通过构造产生均匀采样的Pareto前沿。虽然该算法是通用的,特别感兴趣的是基于仿真的工程最优化问题的经济功能的评估,结果的平滑度和时间的解决方案是至关重要的应用。该算法在求解均匀性方面比其他几何方法(如法向边界求交法和法向约束法)有数量级的提高,且计算量相近。此外,由此产生的解决方案的一致性甚至延伸到更困难的问题,如那些出现在常见的进化算法测试用例。

英文摘要:

A homotopy method for multi-objective optimization that produces uniformly sampled Pareto fronts by construction is presented. While the algorithm is general, of particular interest is application to simulation-based engineering optimization problems where economy of function evaluations, smoothness of result, and time-to-solution are critical. The presented algorithm achieves an order of magnitude improvement over other geometrically motivated methods, like Normal Boundary Intersection and Normal Constraint, with respect to solution evenness for similar computational expense. Furthermore, the resulting uniformity of solutions extends even to more difficult problems, such as those appearing in common Evolutionary Algorithm test cases.
