In this paper, we describe the application of a new type of genetic algorithm called the Structured Genetic Algorithm (sGA) for function optimization in nonstationary environments. The novelty of this genetic model lies primarily in its redundant genetic material and a gene activation mechanism which utilizes a multi-layered structure for the chromosome. In… (More)
Future database applications will require significant improvements in performance beyond the capabilities of conventional disk based systems. This paper describes a new approach to database systems architecture, which is intended to take advantage of solid-state memory in combination with data compression to provide substantial performance improvements. The… (More)
This paper discusses the application of a new genetic search approach called the Structured Genetic Algorithm (sGA) for solving engineering optimization problems. The novelity of this genetic model lies in its hierarchical genomic structure and a gene activation mechanism in its chromosome. Simulation results exhibit its robustness in nding global optima.
