Generational GA Steady - State GAProblem Fitness Evaluations Fitness
Traditional genetic algorithms use operator settings such as the crossover rate or number of crossover points that are xed throughout a given run. The choice of settings can have a major eeect on performance, but nding good settings can be hard. One option is to encode the operator settings onto each member of the GA population, and allow them to evolve too. This paper describes an empirical in...
متن کاملReducing Fitness Evaluations Using Clustering Techniques and Neural Network Ensembles
In many real-world applications of evolutionary computation, it is essential to reduce the number of fitness evaluations. To this end, computationally efficient models can be constructed for fitness evaluations to assist the evolutionary algorithms. When approximate models are involved in evolution, it is very important to determine which individuals should be re-evaluated using the original fi...
متن کاملCo-evolving Fitness Predictors for Accelerating Evaluations and Reducing Sampling
We introduce an estimation of distribution algorithm that co-evolves fitness predictors in order to reduce the computational cost of evolution. Fitness predictors are light objects which, given an evolving individual, heuristically approximate its true fitness. The predictors are trained by their ability to correctly differentiate between good and bad solutions using reduced computation. We app...
متن کاملThe American Psychiatric Association's resource document on guidelines for psychiatric fitness-for-duty evaluations of physicians.
The psychiatric evaluation of a physician's fitness for duty is an undertaking that is both important to patients' well-being and to the physician-subject of the evaluation. It is necessary that psychiatrists who agree to perform such evaluations proceed in a careful and thorough manner. This document was developed to provide general guidance to the psychiatric evaluators in these situations. I...
متن کاملTest acceptability and confidence levels in older adults referred for fitness-to-drive evaluations.
In this study, we examined confidence and face validity or client acceptability of tests used in a Veterans Affairs Medical Center driving clinic. The clinic used evidence-based off-road tests and adopted the Washington University Road Test (WURT) as a performance-based on-road examination. Forty-three clients consented to participate in the study; most were male with an average age of 78.2 yea...
