Determining the arrangement of fictitious charges in charge simulation method using genetic algorithms

In this paper, we propose a method to decide the appropriate arrangement of fictitious charges in the charge simulation method (CSM) by using a direct search method. The appropriate arrangement is achieved by using genetic algorithms (GA) as a search method. We describe the arrangement of the charges as chromosomes and place fictitious point-charges at random on the rotational axis of a spheroidal electrode. The charge arrangement is adjusted by using GA until the potential reaches a specified value over the surface of the electrode.
