Optimization of the compensatory anticathode in the electric fields protection of ship based on evolutionary programming

Electric fields with double compensatory anticathode in the sea were formulated and simulated on the basis of one compensatory anticathode mathematical model and distribution of electric field was analyzed. Number position and current of compensatory anticathode were optimized base on evolutionary programming arithmetic; also electric fields compensated and uncompensated were compared. It shows that the electric fields around ship are reduced obviously by optimizing and the validity of the optimization method based on evolutionary programming arithmetic.
