Abstract
The optimization scheme of the โmulticonfiguration method based on the generalized Brillouin theoremโ (MCGBT) has been analysed and found to converge quadratically. Its rate of convergence has been compared with that of other optimization methods such as the firstโorder RayleighโSchrรถdinger perturbation, the steepest descent, the single vector diagonalization, the NewtonโRaphson, and the conventional SCF method. The convergence of the MCGBT scheme has been found to be superior to the convergence of the above mentioned schemes.

In this paper, two multisplitting methods with K + 1 relaxed parameters are established for solving a linear system whose coefficient matrix is a large sparse M-matrix or H-matrix and the corresponding convergence behaviors are studied. Then the implementation of these two methods with ILU factoriza
