This research proposed 9 modified algorithms for the iterative solver over 30 years ago. Numerical experiments revealed that the speed-up factor of the modified algorithms is more than 5 in conventional boundary element analyses of electromagnetic wave scattering from many objects. Analytical and experimental analyses clarified that the speed-up factor increased with increases in the number of objects and the distance between them. This research also reported superiority of new iterative solvers proposed after 2007 to conventional ones in terms of the net computation time and memory efficiency. Moreover, we provide knowledge for the more than 50 years subject that is the decision of an optimal parameter in the successive overrelaxation method.
