An Incremental Approach to the Proportional GA

by Han Yu, Annie S. Wu
"... The Proportional Genetic Algorithm (PGA) supports truly location independent solution encoding. In this paper, we propose a novel approach, called incremental building blocks, to improve the search performance of PGA. The main idea of this approach is to evolve low level building blocks individually ..."

The Proportional Genetic Algorithm: Gene Expression in a Genetic Algorithm

by Annie Wu, Ivan Garibay - University of Central Florida , 2002
"... We introduce a genetic algorithm (GA) with a new representation method which we call the proportional GA (PGA). The PGA is a multi-character GA that relies on the existence or non-existence of genes to determine the information that is expressed. The information represented by a PGA individual depen ..."

GA: Obesity and reproduction

by George A. Bray - Hum Reprod , 1997
"... Obesity produces a variety of alterations in the reproductive system and, similarly, manipula-tions of the hypothalamic-pituitary-gonadal axis produce changes in food intake, body weight and fat distribution. In men, the primary effects of obesity are a weight related reduction in testosterone and, ..."

/ob) mouse. Leptin is secreted by adipose tissue in proportion to the quantity of fat and may serve as a signal to the hypothalamus that fat stores are adequate to nourish a conceptus to term. In women, parity affects obesity and obesity in turn affects the regularity of the menstrual cycle. In many

Fitness-proportional negative slope coefficient as a hardness measure for genetic algorithms

by Riccardo Poli - in Proceedings of the Genetic and Evolutionary Computation Conference (GECCO-2007 , 2007
"... The Negative Slope Coefficient (nsc) is an empirical measure of problem hardness based on the analysis of offspring-fitness vs. parent-fitness scatterplots. The nsc has been tested empirically on a large variety problems showing considerable reliability in distinguishing easy from hard problems. How ..."
Abstract - Cited by 7 (4 self) - Add to MetaCart
. However, neither a theoretical justification nor a theoretical analysis of the nsc have ever been given. This paper presents a modification of nsc, the fitness-proportional negative slope coefficient (fpncs), for which it is possible to give a theoretical explanation and analysis. To illustrate

Chemical Etching of GaAs

by Sadao Adachi, Kunishige Oe
"... A new HCI:CH3COOH:K2Cr207 system which is particularly suitable for use in etching solutions of GaAs crystals has been developed. This system can be classified into two individual regions, A and B, according to etching characteristics. The solutions in region A are light orange in color, while those ..."

Ordinary mesa-shaped structures have been formed ~n etching stripes in (001) GaAs parallel to the [110] and [110] directions. The system does not erode photo~esists, and so is attractive

Intelligent Automated Control of Life Support Systems Using Proportional Representations

by Annie S. Wu, Ivan I. Garibay , 2004
"... Effective automatic control of Advanced Life Support Systems (ALSS) is a crucial component of space exploration. An ALSS is a coupled dynamical system which can be extremely sensitive and difficult to predict. As a result, such systems can be difficult to control using deliberative and deterministic ..."
Abstract - Cited by 2 (1 self) - Add to MetaCart
. We perform experiments on three ALSS optimization problems using five strategies with multiple variations of a proportional representation for a total of 120 experiments. Results indicate that although a proportional representation can effectively boost GA performance, it does not necessarily have
