On some recent advances in shape optimization

چکیده
In this Note we give a short review on recent developements in shape optimization. We explain how the generic non-existence of solutions can be circumvent. Either one can impose some geometric restrictions on the class of admissible domains to get existence (we then explain how to write the usual optimality conditions), or generalized designs are allowed which leads to relaxation by homogenization techniques (we thus obtain topology optimization methods). 2001 Académie des sciences/Éditions scientifiques et médicales Elsevier SAS solids and structures / shape optimization / existence of optimal shapes / domain derivative / relaxation / topology optimization Sur quelques récents développements de l’optimisation de forme Résumé. Dans cette Note, nous donnons un aperçu de quelques développements récents en optimisation de forme. Nous expliquons comment remédier à la non-existence générique de solutions. On peut imposer des restrictions d’ordre géométrique à la classe des domaines admissibles pour obtenir l’existence (nous expliquons alors comment écrire les conditions d’optimalité). On peut aussi permettre des formes généralisées qui conduisent à la relaxation via les techniques d’homogénéisation (méthodes d’optimisation topologique). 2001 Académie des sciences/Éditions scientifiques et médicales Elsevier SAS solides et des structures / optimisation de forme / existence de forme optimale / dérivée par rapport au domaine / relaxation / optimisation topologique 1.

ON THE FUZZY SET THEORY AND AGGREGATION FUNCTIONS: HISTORY AND SOME RECENT ADVANCES
Several fuzzy connectives, including those proposed by Lotfi Zadeh, can be seen as linear extensions of the Boolean connectives from the scale ${0,1}$ into the scale $[0,1]$. We discuss these extensions, in particular, we focus on the dualities arising from the Boolean dualities. These dualities allow to transfer the results from some particular class of extended Boolean functions, e.g., from c...
متن کاملRecent Advances in Structural Optimization
In this paper we present the main directions of research in Structural Convex Optimization. In this field, we use additional information on the structure of specific problem instances for accelerating standard Black-Box methods. We show that the proper use of problem structure can provably accelerate these methods by the order of magnitudes. As examples, we consider polynomialtime interior-poin...
متن کاملTHIN WALLED STEEL SECTIONS’ FREE SHAPE OPTIMIZATION USING CHARGED SYSTEM SEARCH ALGORITHM
Graph theory based methods are powerful means for representing structural systems so that their geometry and topology can be understood clearly. The combination of graph theory based methods and some metaheuristics can offer effective solutions for complex engineering optimization problems. This paper presents a Charged System Search (CSS) algorithm for the free shape optimizations of thin-wall...
