Abstract

Optimization plays a critical role in fields such as economics, engineering, and computational sciences, where finding the optimal values of decision variables is essential for the design of a product, production system, or service system. However, many optimization problems remain challenging even with advanced solvers. This study integrates machine learning into optimization by employing a regression tree algorithm that is trained on sampled solutions of the problem to improve the efficiency of derivative-free nonlinear programming solvers. The approach is tested on 24 single-objective functions to reduce the domain of decision variables. The results demonstrate better accuracy and consistency in the solver performance. Incorporating a machine learning technique into an optimization method can be extended to solve black-box optimization problems and paves the way for innovative solutions in engineering design and other domains.

利用回归树提高非线性规划求解器的效率

优化在经济学、工程学和计算科学等领域起着至关重要的作用，在这些领域中，找到决策变量的最优值对于产品、生产系统或服务系统的设计至关重要。然而，即使有先进的求解器，许多优化问题仍然具有挑战性。本研究通过采用回归树算法将机器学习集成到优化中，该算法在问题的采样解上进行训练，以提高无导数非线性规划求解器的效率。该方法在24个单目标函数上进行了测试，以减少决策变量的域。结果表明，求解器的性能具有较好的准确性和一致性。将机器学习技术整合到优化方法中可以扩展到解决黑盒优化问题，并为工程设计和其他领域的创新解决方案铺平道路。
