Genetic algorithms for cluster optimization: general aspects
|Roy L. Johnston|
School of Chemistry, University of Birmingham, Edgbaston, Birmingham B152TT, United Kingdom
In this lecture, I will start by giving a short overview of the field of cluster science and the reasons for using genetic algorithms for global optimization in this field. I will then present a brief history of the application of genetic algorithms to various types of clusters. Finally, I will describe the development of our own genetic algorithm (the Birmingham Cluster Genetic Algorithm) for cluster geometry optimization - giving examples of its application to a variety of different types of clusters.
During the lecture, I will emphasize how the nature of the problem or system being studied influences our choice of genetic algorithm methodology and operators and I will introduce a number of ways in which the basic genetic algorithm can be improved - for example by developing hybrid search methodologies to enable local as well as global searching. I will also talk about potential pitfalls and possible future directions.
