Mirrored Orthogonal Sampling for Covariance Matrix Adaptation Evolution Strategies

open access: yesEvolutionary Computation, 2019
Generating more evenly distributed samples in high dimensional search spaces is the major purpose of the recently proposed mirrored sampling technique for evolution strategies. The diversity of the mutation samples is enlarged and the convergence rate is therefore improved by the mirrored sampling.

Improving (1+1) covariance matrix adaptation evolution strategy: A simple yet efficient approach [PDF]

open access: yesAIP Conference Proceedings, 2019
In recent years, part of the meta-heuristic optimisation research community has called for a simplification of the algorithmic design: indeed, while most of the state-of-The-Art algorithms are characterised by a high level of complexity, complex algorithms are hard to understand and therefore tune for specific real-world applications.

Two-Stage Intelligent Layout Design of Curved Cabin Door

open access: yesAerospace, 2023
As one of the most complex and critical components of spacecraft, the structural design of the curved cabin door faces two challenges. On the one hand, it is difficult to obtain innovative configurations for the cabin door in the preliminary design stage.

Source mask optimization using the covariance matrix adaptation evolution strategy

open access: yesOptics Express, 2020
Source mask optimization (SMO) is one of the indispensable resolution enhancement techniques to guarantee the image fidelity and process robustness for the 2Xnm technology node and beyond. The optimization capacity and convergence efficiency of SMO are important, especially for full-chip SMO.

Comparing Mirrored Mutations and Active Covariance Matrix Adaptation in the IPOP-CMA-ES on the Noiseless BBOB Testbed [PDF]

open access: yes, 2012
International audienceThis paper investigates two variants of the well-known Covariance Matrix Adaptation Evolution Strategy (CMA-ES). Active covariance matrix adaptation allows for negative weights in the covariance matrix update rule such that "bad ...

Black-Box Optimization Using Geodesics in Statistical Manifolds

open access: yesEntropy, 2015
Information geometric optimization (IGO) is a general framework for stochastic optimization problems aiming at limiting the influence of arbitrary parametrization choices: the initial problem is transformed into the optimization of a smooth function on a
