This paper illustrates the application of forest optimization technique for the determination of optimal finite impulse response (FIR) filter parameters.With the inputs being the design specifications, an attempt to apply the forest optimization algorithm for highly nonlinear, constrained optimization problem of filter design has been made.Optimization of filter parameters is done by exploiting the natural evolution of trees in a forest.Local seeding has been used for Local searching and global seeding concept ensures that only global solution is reached without falling into local optimum.In contrast to the conventional windowing techniques generally employed, this method realizes the ideal frequency characteristics meeting the specified targets related to pass band filter and stop band.Simulation results are presented.
