In this paper, we first propose and formulate a novel approach in Particle Swarm Optimization (which we call "Particle Swarm Optimization with Parameter Dependency Walls") for handling the dependencies between the design parameters. After revisiting the definition of Particle Swarm Optimization; we try to visualize the physical meaning of the concepts lying beneath our approach, and demonstrate the existence of analytical solution needed throughout the implementation. In order to illustrate a practical application of our approach, we first revisit the empirical closed-form characteristic impedance expression for the microstrip-like interconnect line with a ground plane aperture. Then, we apply our approach in order to calculate the optimized parameters of microstrip-like interconnect lines in the synthesis problem. The proposed procedure can be useful for the rapid solution of the optimization problems in which there exist dependencies between/among the input variables. (C) 2011 Elsevier GmbH.
