Constructor & Destructor Documentation

__init__()

def convergence_accelerators.anderson.AndersonConvergenceAccelerator.__init__	(		self,
			settings
	)

The constructor.

Parameters

iteration_horizon	number of values to be stored of last iterations.
alpha	Relaxation factor for computing the update.
beta	weighting factor of constant relaxation
p	factor for switch between constant relaxation and alternating anderson Gauß-Seidel/Jacobian method p = 1 results in the Anderson acceleration and p -> infinity results in constant relaxation
