Multi-objective optimisation of damper placement in dynamically symmetric\nadjacent buildings is considered with identical viscoelastic dampers used for\nvibration control. First, exhaustive search is used to describe the solution\nspace in terms of various quantities of interest such as maximum top floor\ndisplacement, maximum floor acceleration, base shear, and interstorey drift.\nWith the help of examples, it is pointed out that the Pareto fronts in these\nproblems contain a very small number of solutions. The effectiveness of two\ncommonly used multi-objective evolutionary algorithms, viz., NSGA-II and MOPSO,\nis evaluated for a specific example.\n
