Disk2Planet: A Robust and Automated Machine Learning Tool for Parameter Inference in Disk–Planet Systems

The Astrophysical Journal
We introduce Disk2Planet, a machine-learning-based tool to infer key parameters in disk–planet systems from observed protoplanetary disk structures. Disk2Planet takes as input the disk structures in the form of 2D density and velocity maps, and outputs ...

Adaptive Ranking Based Constraint Handling for Explicitly Constrained Black-Box Optimization

, 2019
A novel explicit constraint handling technique for the covariance matrix adaptation evolution strategy (CMA-ES) is proposed. The proposed constraint handling exhibits two invariance properties.

A parallel implementation of the covariance matrix adaptation evolution strategy

, 2018
In many practical optimization problems, the derivatives of the functions to be optimized are unavailable or unreliable. Such optimization problems are solved using derivative-free optimization techniques. One of the state-of-the-art techniques for derivative-free optimization is the covariance matrix adaptation evolution strategy (CMA-ES) algorithm ...

Data-Driven Topology Optimization With Warm Starting CMA-ES for Constraint Optimization in Rotating Machines

IEEE Access
In this paper, a novel topology optimization method, which reduce the computational cost for solving constrained optimization, was proposed. In constrained optimization problems, it takes a lot of time to search for solutions that satisfy the constraints

Neutrality: A Necessity for Self-Adaptation

, 2002
Self-adaptation is used in all main paradigms of evolutionary computation to increase efficiency. We claim that the basis of self-adaptation is the use of neutrality.
