Application of immune algorithm with searching diversity to arrangement problem of fictitious chareges and contour points for charge simulation method

摘要

When the charge simulation method is used for electric field analyses, an appropriate arrangement of both fictitious charges and contour points is indispensable to obtain an accurate solution. However, when they are placed three dimensionally (3D), it is very difficult to obtain such an arrangement even if a conventional searching method, such as Genetic Algorithm, is adopted because the searching area for 3-D case is remarkably wide. In this paper, we adopt Immune Algorithm (IA) with a high searching performance to this 3-D arrangement problem. By using IA, an accurate 3-D potential distribution around the electrodes is automatically obtained in high probability.
