scipy.optimize.anderson

scipy.optimize.anderson(F, xin, iter=10, alpha=0.10000000000000001, M=5, w0=0.01, verbose=False)

Extended Anderson method.

Computes an approximation to the inverse Jacobian from the last M interations. Avoids NxN matrix multiplication, it only has MxM matrix multiplication and inversion.

M=0 .... linear mixing M=1 .... Anderson mixing with 2 iterations M=2 .... Anderson mixing with 3 iterations etc. optimal is M=5
