Description	This paper describes the application of the particle swarm optimization to the shape optimization of two-dimensional domains described by NURBS and analyzed using the NURBS-based isogeometric analysis. The regularization of the optimization problem, preventing undesirable clustering of control points of the underlying geometry leading to invalid geometry or parametrization, is achieved by controlling the magnitude of perturbation of design variables within the PSO using a background mesh. This mesh, however, does not have to comply with requirements on a standard (e.g. finite element) computational mesh, as it does not have to follow the exact geometry. Thus construction of such a mesh is simple and does not introduce a bottleneck to the whole process. The capabilities and performance of the developed optimization strategy are demonstrated on standard benchmark problems.
