论文摘要
受限的优化问题可能很困难,因为它们的搜索空间具有不利于搜索的属性,例如多模式,不连续性或欺骗。为了解决此类困难,已经对创建新型进化算法或专门的遗传操作员进行了大量研究。但是,如果可以更改定义搜索空间的表示形式,以便仅允许满足约束的有效解决方案,则在无需任何专业优化算法的情况下,找到最佳的任务将变得更加可行。我们提出了潜在空间(COIL)的约束优化,该优化使用VAE从数据集中从搜索空间的有效区域组成样本的数据集中生成了学习的潜在表示,从而使优化器使优化器能够在由学识渊博的表示定义的新空间中找到目标。初步实验表明了前景:与使用无法满足约束或找到适合解决方案的标准表示相同的GA相比,具有其学习潜在表示的线圈可以完美地满足不同类型的约束,同时找到高素质解决方案。
Constrained optimization problems can be difficult because their search spaces have properties not conducive to search, e.g., multimodality, discontinuities, or deception. To address such difficulties, considerable research has been performed on creating novel evolutionary algorithms or specialized genetic operators. However, if the representation that defined the search space could be altered such that it only permitted valid solutions that satisfied the constraints, the task of finding the optimal would be made more feasible without any need for specialized optimization algorithms. We propose Constrained Optimization in Latent Space (COIL), which uses a VAE to generate a learned latent representation from a dataset comprising samples from the valid region of the search space according to a constraint, thus enabling the optimizer to find the objective in the new space defined by the learned representation. Preliminary experiments show promise: compared to an identical GA using a standard representation that cannot meet the constraints or find fit solutions, COIL with its learned latent representation can perfectly satisfy different types of constraints while finding high-fitness solutions.
