A hybrid intelligent genetic algorithm for truss optimization based on deep neutral network
2022, Swarm and Evolutionary ComputationCitation Excerpt :Similarly, the integrated optimization of truss structures has been investigated in literature [30–33]. Apart from considering different optimization parameters, various truss optimization problems have been investigated, such as the compliance minimization problem [34,35] and the weight minimization problem [22,36,37]. In addition, more complex optimization problems have also been studied, such as the dynamic optimization problem [38–41], the buckling optimization problem [42,43] and so on [44,45].
Quantile-based sequential optimization and reliability assessment for shape and topology optimization of plane frames using L-moments
2022, Structural SafetyCitation Excerpt :On the other hand, since the adjustment of nodal locations can usually lead to effective improvement of objective function value [43,44], one can start from a sparse ground structure if the shape optimization is involved. However, when the nodes are allowed to move in a wide range of the design space, one of the main difficulties is the existence of melting nodes or coalescent nodes which results in extremely short members in the structure and makes the stiffness matrix singular [45,46]. To alleviate the problem caused by melting nodes, Ohsaki and Hayashi [47,48] explored the merit of force density method (FDM) to shape and topology optimization of pin-jointed trusses, in which the objective and constraint functions are expressed explicitly by force density only, and Shen and Ohsaki [49] extended the method to the optimization of rigidly-jointed frames.

2014, Engineering StructuresCitation Excerpt :Bojczuk [4] studied the optimal topology and configuration design of trusses with stress and buckling constraints. Ohsaki [5] and Burns [6] presented a simultaneous optimization method for topology and geometry of a regular plane truss, and he considered the nodal cost for structural topology. Wang et al. [7] developed a sensitivity analysis method based on nodal coordinates with multiple displacement constraints.
Topology optimization for the seismic design of truss-like structures
2011, Computers and StructuresCitation Excerpt :These methods represent general adaptive search techniques that simulate natural inheritance by adapting appropriate models based on genetics and natural selection. Computational effort that is associated with GAs seems to be high even for optimizing large elastic truss structures under static loads [16]. Therefore, it is not realistic to use these algorithms for optimum seismic design of truss structures in the practice.
