    摘要:

    提出了一种评估近似Pareto前沿多样性的方法.它用精确Pareto前沿相对于其近似集合的"暴露程度"来评估多样性,其计算基于精确Pareto前沿,不像其他多样性评估技术基于近似集合进行计算.对于多于两个目标(分量)的近似集合,其他技术不能或者不能很好地评估,计算结果表明,该技术能够很好地评估.并且,在理论上对该方法进行了严格的论证.

    Abstract:

    This paper introduces a new technique for assessing the diversity of approximation of exact set. The diversity is assessed by the "exposure degree" of the exact set against the approximation set in the new technique where the projection of the approximation set on the exact set, not the approximation set, is used to cover the exact set. Therefore, the new technique still works well for the problems with 3 and more objectives, significantly improving the existing techniques. Computational results show that it assesses the diversity well. Rigorous analysis is made for the new method.
