Hybrid high-order and weak Galerkin methods for the biharmonic problem

Z Dong, A Ern - SIAM Journal on Numerical Analysis, 2022 - SIAM
We devise and analyze two hybrid high-order (HHO) methods for the numerical
approximation of the biharmonic problem. The methods support polyhedral meshes, rely on …

An arbitrary-order method for magnetostatics on polyhedral meshes based on a discrete de Rham sequence

Harris hawks optimizer based on the novice protection tournament for numerical and engineering optimization problems

W Li, R Shi, J Dong - Applied Intelligence, 2023 - Springer
The Harris hawks optimizer (HHO) is a novel meta-heuristic algorithm that imitates a Harris
hawk's hunting behavior and has an efficient exploitation mode. However, it suffers from low …
