A modified Covariance Matrix Adaptation Evolution Strategy with adaptive penalty function and restart for constrained optimization

Posted on 28 de January de 2015 by admin Posted in CMAES, Constrained Optimization, Engineering Design, Evolutionary algorithm, Journal, Metaheuristic, Self-adaptive

In the last decades, a number of novel meta-heuristics and hybrid algorithms have been proposed to solve a great variety of optimization problems. Among these, constrained optimization problems are considered of particular interest in applications from many different domains. The presence of multiple constraints can make optimization problems particularly hard to solve, thus imposing the

Comparison of linear genetic programming variants for symbolic regression

In this paper, we compare a basic linear genetic programming (LGP) algorithm against several LGP variants, proposed by us, on two sets of symbolic regression benchmarks. We evaluated the influence of methods to control bloat, investigated these techniques focused in growth of effective code, and examined an operator to consider two successful individuals as modules

Kaizen Programming

This paper presents Kaizen Programming, an evolutionary tool based on the concepts of Continuous Improvement from Kaizen Japanese methodology. One may see Kaizen Programming as a new paradigm since, as opposed to classical evolutionary algorithms where individuals are complete solutions, in Kaizen Programming each expert proposes an idea to solve part of the problem, thus

Investigating multi-view differential evolution for solving constrained engineering design problems

Posted on 14 de January de 2013 by admin Posted in Constrained Optimization, Differential evolution, Engineering Design, Evolutionary algorithm, Journal, Metaheuristic, Multi-view

Several constrained and unconstrained optimization problems have been adequately solved over the years thanks to advances in the metaheuristics area. In the last decades, different metaheuristics have been proposed employing new ideas, and hybrid algorithms that improve the original metaheuristics have been developed. One of the most successfully employed metaheuristics is the Differential Evolution. In

Evolutionary algorithms and HP Model for protein structure prediction

Posted on 14 de January de 2013 by admin Posted in Evolutionary algorithm, Global Continuous Unconstrained Optimization, Journal, Metaheuristic, Multi-objective, Protein structure prediction

Protein structures prediction (PSP) is a computationally complex problem. Simplified models of the protein molecule (such as the HP Model) and the use of evolutionary algorithms (EAs) are among the most investigated techniques for PSP. However, the evaluation of a structure represented by the HP model considers only the number of hydrophobic contacts, which doesn’t
