GLOBAL OPTIMIZATIONDIRECT SEARCHALGORITHMFor the unconstrained optimization of black box functions, this paper introduces a new randomized algorithm called VRBBO. In practice, VRBBO matches the quality of other state-of-the-art algorithms for finding, in small and large dimensions, a local minimizer ...
Modelling human function learning has been the subject of intense research in cognitive sciences. The topic is relevant in black-box optimization where information about the objective and/or constraints is not available and must be learned through function evaluations. In this paper, we focus on ...
There are a large number of engineering optimization problems in real world, whose input-output relationships are vague and indistinct. Here, they are called black box function optimization problem (BBFOP). Then, inspired by the mechanism of neuroendocrine system regulating immune system, BP neural ...
背景:研究约束有效全局优化问题,目标和约束都是昂贵黑盒函数。对于常用的M´atern和Squared指数核,我们的边界是次线性的,允许我们推导出一个收敛率到原始约束问题的最优解。 方法:用高斯过程来学习。约束有效全局优化。 成果:在一定的规则性假设下,证明了我们的算法具有与无约束情况相同的累积遗憾界和相似的累积约束...
This edited volume illustrates the connections between machine learning techniques, black box optimization, and no-free lunch theorems. Each of the thirteen contributions focuses on the commonality and interdisciplinary concepts as well as the fundamentals needed to fully comprehend the impact of individual...
黑盒优化面临最大的问题就是“收敛性”问题,它是不依赖梯度的(Derivative Free Optimization Approach),只关心输入的动作和输出的奖励,如何保证收敛性?讨论收敛性问题显然超出了本文的讨论范畴,庆幸的是我们生活的宇宙恰好能够使这类算法几乎收敛,这种优化方法跟进化算法(EA)十分相似,而且 worksembarrassinglywell 。
blackbox: A Python module for parallel optimization of expensive black-box functions What is this? A minimalistic and easy-to-use Python module that efficiently searches for a global minimum of an expensive black-box function (e.g. optimal hyperparameters of simulation, neural network or anything...
To address these issues, we propose leveraging Covariance Matrix Adaptation Evolution Strategy (CMA-ES) to enhance RL-based EMS for effective black-box optimization. By integrating an opponent reference mechanism and a self-balanced reward function, our approach aims to provide a more stable and eff...
