Bidirectional evolutionary method for stiffness optimization

A Procedure for the Detailing Design of Simply Supported R.C. Bridge Decks Subjected to in-Plane Actions

“…If too much material is removed in one step, the ESO method is unable to restore the elements which might have been prematurely deleted at earlier iterations. In order to make the ESO method more robust, a Bi-directional ESO method (BESO) was proposed by Yang et al [24]. It allows for efficient materials to be added to the structure at the same time as the inefficient ones are being removed.…”

A Novel Approach to Design Lesion-Specific Stents for Minimum Recoil

“…Various approaches have been proposed for TO [25][26][27][28][29][30][31][32][33], which is gaining attention in a wide variety of applications. TO based contact analysis of stent and diseased artery is a novel approach to take into account the accurate loading conditions of different plaque types to customise stent architectures according to specific lesions while maintaining vessel lumen area.…”

An improved soft-kill BESO algorithm for optimal distribution of single or multiple material phases

“…The BESO method was originally introduced by Querin et al (1998) and Yang et al (1999) as a successor of the Evolutionary Structural Optimization (ESO) method which was proposed by Xie and Steven (1993). After discretizing the design domain using finite element method, to evolve the structure towards an optimal topology, BESO iteratively introduces new elements to efficient parts of the design domain and removes its inefficient elements.…”
