Parameter Setting in EAs: a 30 Year Perspective

نویسنده

  • Kenneth DeJong
چکیده

Parameterized evolutionary algorithms (EAs) have been a standard part of the Evolutionary Computation community from its inception. The widespread use and applicability of EAs is due in part to the ability to adapt an EA to a particular problem-solving context by tuning its parameters. However, tuning EA parameters can itself be a challenging task since EA parameters interact in highly non-linear ways. In this chapter we provide a historical overview of this issue, discussing both manual (human-in-the-loop) and automated approaches, and suggesting when a particular strategy might be appropriate.

Combining Meta-EAs and Racing for Difficult EA Parameter Tuning Tasks

This chapter presents a novel framework for tuning the parameters of Evolutionary Algorithms. A hybrid technique combining Meta-EAs and statistical Racing approaches is developed, which is not only capable of effectively exploring the search space of numerical parameters but also suitable for tuning symbolic parameters where it is generally difficult to define any sensible distance metric.

Parameter Setting in Evolutionary Algorithms applied to the Multiobjectivised Frequency Assignment Problem

Metaheuristics is a family of approximation algorithms widely used to deal with optimisation problems. Among them, Evolutionary Algorithms (EAs) are one of the most popular approaches. They usually have several components (genetic operators, selection operator, etc.) and parameters (mutation rate, crossover rate, etc.) which must be fixed. Therefore, one of the main drawbacks of EAs is the comp...

Web-Based education accountability system and Organisational Changes

The learning and accountability needs in a teacher education department drove the development of a novel Web-based education accountability system (EAS). To fit the EAS with the organization, actor-network theory (ANT) was used to guide the social and technological development. In the course of fitting the technology to the educational setting, a novel multi-dimensional perspective to ANT was f...
