查询词典 Ga.

A 2-D coded GA is proposed to design the matching network composed of lumped components. The topology and component parameters of the matching network are optimized simultaneously. The network optimized by employing the 2-D coded GA shows better frequency response compared with the network synthesis method and the real frequency method. The thesis also employs the GAs to microwave measurement.
