gradient free optimization综述Gradient Free Optimization(无梯度优化算法)是一种优化方法,它不需要目标函数可导,适用于离散的不连续或者其他非连续问题。最常用的无梯度优化算法有遗传算法、粒子群算法、模拟退火算法和Nelder- Mead simplex algorithm。 具体来说,遗传算法是基于生物进化原理的一种优化算法,通过模拟基因...

A Gray code based gradient-free optimization(GCO)algorithm is proposed to update the parameters of parameterized quantum circuits(PQCs)in this work.Each parameter of PQCs is encoded as a binary string,named as a gene,and a genetic-based method is adopted to select the offsprings.The individuals...
between the holes can get too thin, also leading to high stresses. Therefore, we must monitor the maximum stress throughout the part, and constrain this to be below a specified peak stress. This is a non-differentiable constraint, and it specifically requires the gradient-free optimization ...
Gradient-Free-Optimizers is extensivly tested with more than 400 tests in 2500 lines of test code. This includes the testing of: Each optimization algorithm Each optimization parameter All attributes that are part of the public api Performance test for each optimizer ...
Our particular focus is on optimization problems for which direct gradient estimates are not available, and that instead must be approximated using estimates of the objective function. The classic Kiefer-Wolfowitz algorithm, using stepsize-control, is one such algorithm that estimates a divided ...

Mathematics - Optimization and ControlIn the paper we generalize universal gradient method (Yu. Nesterov) to strongly convex case and to Intermediate gradient method (Devolder-Glineur-Nesterov). We also consider possible generalizations to stochastic and online context. We show how these results can...
