Removingthe good initial guess required for the solving eigenvalue problem, we replace the downhillsimplex method with the Sakurai-Sugiura projection method (SSM) which is one ofnonlinear eigenvalue problem solvers. Therefore, we may compute all eigenvalues in thescope without time-consuming preparations for the initial guess.
