Topology optimization has evolved rapidly since the late 1980s. The optimization of the
geometry and topology of structures has a great impact on its performance, and the last two …

The paper reviews options for structural design sensitivity analysis, including global finite
differences, continuum derivatives, discrete derivatives, and computational or automated …

Describes development work to combine the basic ESO with the additive evolutionary
structural optimisation (AESO) to produce bidirectional ESO whereby material can be added …

This paper examines the application of neural networks (NN) to reliability-based structural
optimization of large-scale structural systems. The failure of the structural system is …

The evolutionary structural optimisation (ESO) method has been under continuous
development since 1992. Originally the method was conceived from the engineering …

The objective of this paper is to investigate the efficiency of combinatorial optimization
methods, in particular algorithms based on evolution strategies (ES) when incorporated into …

The objective of this paper is to investigate the efficiency of various evolutionary algorithms
(EA), such as genetic algorithms and evolution strategies, when applied to large-scale …

The evolutionary structural optimisation (ESO) method has been under continuous

This paper describes a methodology which combines finite element analysis and
Zoutendijk's feasible directions method for mufflers shape design. The main goal is to obtain …

This paper proposes a new high-efficiency isogeometric topology optimization (HITO),
including three part: multilevel mesh, multigrid conjugate gradient method (MGCG) and local …
