A Tractable Robust Topology Optimization for Anomalous Non-Symmetric Cases

Proceedings of the Sixth International Conference on Soft Computing, Machine Learning and Optimisation in Civil, Structural and Environmental Engineering, 2023
In the practice of robust optimality design, robust and deterministic optimal configurations are usually expected to differ. Therefore, most research in this area tries to illustrate the effect of uncertainty by comparing robust and deterministic designs,

A hybrid multiagent approach for global trajectory optimization [PDF]

, 2008
In this paper we consider a global optimization method for space trajectory design problems. The method, which actually aims at finding not only the global minimizer but a whole set of low-lying local minimizers(corresponding to a set of different design

A novel dynamic reliability-based topology optimization (DRBTO) framework for continuum structures via interval-process collocation and the first-passage theories

Computer Methods in Applied Mechanics and Engineering, 2021
In view of the general inertia and damping features as well as the inevitable uncertainty factors in engineering structures, a novel dynamic reliability-based topology optimization (DRBTO) strategy is investigated for time-variant mechanical systems with
