✦ Synopsis

In this paper, we use a genetic-algorithm GA technique to optimize equi¨alent-circuit models of an antenna system. Two broadband equi¨alent-circuit models with component ¨alues are optimized by use of the genetic algorithm. The first is a con¨entional RLC network, while the second introduces a new technique that makes use of transmission-line segments as well as lumped components. Both equi¨alent circuits exhibit good impedance fidelity o¨er a bandwidth exceeding fi¨e octa¨es, including the fundamental through the fourth o¨ertone response.

A Genetic Algorithm (GA) is described, which produces solutions to the cost optimization problem of reinforcement layout for reinforced soil slopes. These solutions incorporate di!erent types of reinforcement within a single slope. The GA described is implemented with the aim of optimizing the cost

To obtain the maximum output power of a copper ¨apor laser, the LC parameter configuration of a discharge circuit is optimized by applying a genetic algorithm. The optimized LC parameter configuration is found to be C s 7.26 nF, C s 6.74 nF, L s 1.28 H, and d p d L s 0.32 H. The laser power has been
