This paper presents an application of estimation of distributed algorithms to the job shop scheduling with the objective to minimize tardiness of jobs. The priority values for job selection are coded as genes and estimated by EDAs. Three kinds of methods for estimating the priorities are tested. In addition, the optimization method using the mixture of EDA and an effective priority rule for job selection...
This paper describes the wideband limitation of planar rectangular disc antennas and its downsizing limitation. Here, planar rectangular disc antennas such as a card type antenna are considered. The card antenna is composed of metal pieces and is designed by using Genetic Algorithm. On the basis of the parameter study, the limitations of the relative bandwidth and the lowest frequency of such antennas...
