This paper presents a constraint handling approach without the need to use a penalty function, namely Optimization Without Penalty (OWP). This approach is used on a recent optimization algorithm based on morphological filters, called Optimization by Morphological Filters (OMF). This work consists of providing a simple and effective constraint-handling approach without the necessity of the penalty for any considered optimization problem. The proposed approach is applied to 03 hard mathematical functions, 18 benchmark constraint functions presented in CEC 2010 competition on constrained real-parameter optimization, and 7 constrained engineering design problems reported in the specialized literature. According to the statistical comparison results, the performance of the OMF algorithm with OWP-based approach is better or highly competitive on most of the studied problems.

无惩罚地解决工程优化问题

本文提出了一种无需使用惩罚函数的约束处理方法，即优化无惩罚（OWP）。这种方法用于最近基于形态过滤器的优化算法，称为形态过滤器优化 (OMF)。这项工作包括提供一种简单有效的约束处理方法，而无需对任何考虑的优化问题进行惩罚。所提出的方法应用于 03 个硬数学函数、CEC 2010 约束实参数优化竞赛中提出的 18 个基准约束函数，以及专业文献中报告的 7 个约束工程设计问题。根据统计比较结果，
