Digital IIR Filter Design Using a Differential Evolution Algorithm with Polar Coordinates
Peter A. Stubberud · 2022 IEEE 12th Annual Computing and Communication Workshop and Conference (CCWC) · 2022
A differential evolution algorithm is presented that uses a combination of rectangular and polar coordinates. The algorithm was developed using thirteen commonly used numerical optimization test functions, including a spherical, three hyper-ellipsoid, the sum of different powers, Rastrigin's, Schwefel's, Griewank's, Rosenbrock's valley, Styblinski- Tang, Ackley's Path, Price- Rosenbrock, and Eggholder's functions. The algorithm was then applied to design a digital infinite impulse response (IIR) filter.
