Multiobjective topology optimization of truss structures with kinematic stability repair

Quantum-Inspired Evolutionary Algorithm for Topology Optimization of Modular Cabled-Trusses

“…Among the main types of optimization, size and shape optimization are mature areas of research that have received considerable attention [19]. Topology optimization, on the other hand, still faces several challenges [5,18]. This is because topology variables are discrete; therefore, the direct application of the traditional gradient-based optimization techniques is not possible [18].…”

“…Topology optimization, on the other hand, still faces several challenges [5,18]. This is because topology variables are discrete; therefore, the direct application of the traditional gradient-based optimization techniques is not possible [18]. The presence of discrete variables in topology optimization of discrete structures led to the use of stochastic search methods [20], such as simulated annealing [21], evolution strategies [22], particle swarm optimizer [23], ant colony optimization [24], harmony search method [25], and genetic algorithm [26], among others.…”

“…The optimal design of discrete structures has been actively investigated in the last decades, and significant progress has been made in both optimality criteria and solution techniques [7,[15][16][17][18]. Among the main types of optimization, size and shape optimization are mature areas of research that have received considerable attention [19].…”

Interactive truss design using Particle Swarm Optimization and NURBS curves

“…Fourie and Groenwold were the first to apply the particle swarm optimization (PSO) method for the design of truss structures, confirming its efficiency compared to GAs [26]. Since then, many variations of the algorithm, when applied to structural optimization, have been proposed and implemented [27,28,29,30,31]. Recently, hybrid algorithms have started to emerge, such as cellular automata and particle swarm optimization [32].…”

Mixed Approaches to Handle Limitations and Execute Mutation in the Genetic Algorithm for Truss Size, Shape and Topology Optimization

“…Different variants of GAs, adapted to the structural optimization problems, are presented in Refs. [14][15][16][17][18][19][20][21][22][23] and in many other works. Algorithms for optimal design of constructions combining GAs procedures with other methods of structure optimization were also considered [24][25][26][27].…”
