“…The third group consists of heuristic methods, among which one can list the fol ing: sequential search algorithm (SSA) [385], pattern search algorithm (PSA) [380], unif Various methods can be used to determine the optimal location of dampers in a structure. They can be divided into main groups: evolutionary methods, analytical methods, and heuristic methods [16].…”

“…Typically, in evolutionary approaches, such as the genetic algorithm (GA) [378][379][380], the artificial bee colony algorithm (ABCA) [376], or particle swarm optimization (PSO) [71,381], different starting points are selected and then the best solution is searched for sequentially. Such a search without calculating the gradient can lead to local optima, especially when there is little variation in the value of the cost function in the domain of design variables.…”

“…The basic idea of the PSA method is to use steps of a certain magnitude to sample variables and reduce their size when the variation of the function value is stopped [380]. This method is suitable for problems in which the function cannot be differentiated or is not continuous.…”

The paper is devoted to a review of recent achievements in the field of dynamic analysis of structures and structural elements, such as beams and plates, with embedded viscoelastic (VE) dampers and/or layers. The general characteristics of VE materials, their rheological models, and methods of parameters identification are discussed. New formulations of dynamic problems for systems with VE elements are also reviewed. The methods of determination of dynamic characteristics, together with the methods of analysis of steady-state and transient vibrations of such systems, are also discussed. Both linear and geometrically non-linear vibrations are considered. The paper ends with a review of the methods of sensitivity and uncertainty analysis, and the methods of optimization, for structures with VE elements.
