A novel hybrid genetic algorithm (HGA) is proposed to jointly optimize all subfilters in a discrete space. The proposed HGA introduces the simulated annealing technique into the genetic algorithm (GA) optimization process and effectively prevents the GA from prematurely converging. It is shown, by means of examples, that FRM filters designed by the HGA achieve a significant reductionin the number of bits. © Birkhauser Boston 2006.||Source Title:||Circuits, Systems, and Signal Processing||URI:||http://scholarbank.nus.edu.sg/handle/10635/56228||ISSN:||0278081X||DOI:||10.1007/s00034-005-2502-8|
