Abstract: ESO-type topology optimization methods are re-examined and several improvements are suggested. Owing to objection to the term Evolutionary Sturctural Optimisation, the modified solution strategy will be termed SERA (Sequential Element Rejections and Admissions).

Keywords: Evolutionary Structural Optimization (ESO); compliance design, stress design; rejection criteria; admission criteria; Lagrange multipliers; optimality criteria; linear approximation; Sequential Element Rejections and Admission (SERA).
