Abstract

Methods of evolutionary structural optimization (ESO) topology are reviewed. The modified solution strategy is termed as Sequential Element Rejections and Admissions (SERA) due to objections to the ESO term. Improvement of ESO for overcoming certain computational pitfalls are suggested. Solid isotropic microstructures with penalization for intermediate densities (SIMP) is considered to be the most efficient method for solid-empty topologies.
