An Improved Unordered Pair Bat Algorithm for Solving the Symmetrical Traveling Salesman Problem

open access: yesFoundations of Computing and Decision Sciences, 2022
Bat algorithm is an effective swarm intelligence optimization algorithm which is widely used to solve continuous optimization problems. But it still has some limitations in search process and can’t solve discrete optimization problems directly. Therefore,

Symmetric Nonnegative Matrix Factorization Based on Box-Constrained Half-Quadratic Optimization

open access: yesIEEE Access, 2020
Nonnegative Matrix Factorization (NMF) based on half-quadratic (HQ) functions was proven effective and robust when dealing with data contaminated by continuous occlusion according to the half-quadratic optimization theory.

The quantum marginal problem for symmetric states: applications to variational optimization, nonlocality and self-testing [PDF]

open access: yesNew Journal of Physics, 2020
In this paper, we present a method to solve the quantum marginal problem for symmetric d-level systems. The method is built upon an efficient semi-definite program that uses the compatibility conditions of an m-body reduced density with a global n-body ...

Symmetrized semi-discrete optimal transport

open access: yes, 2022
Interpolating between measures supported by polygonal or polyhedral domains is a problem that has been recently addressed by the semi-discrete optimal transport framework. Within this framework, one of the domains is discretized with a set of samples, while the other one remains continuous.

Optimizing the HSX stellarator for microinstability by coil-current adjustments

open access: yesNuclear Fusion, 2023
The optimization of helically symmetric experiment (HSX) for reduced microinstability has been achieved by examining a large set of configurations within a neighborhood of the standard operating configuration.
