SimPEG.optimization.InexactGaussNewton#

class SimPEG.optimization.InexactGaussNewton(**kwargs)[source]#

Bases: SimPEG.optimization.BFGS, SimPEG.optimization.Minimize, SimPEG.optimization.Remember

Minimizes using CG as the inexact solver of

Hp=−g

By default BFGS is used as the preconditioner.

Use nbfgs to set the memory limitation of BFGS.

To set the initial H0 to be used in BFGS, set bfgsH0 to be a SimPEG.Solver

Attributes

approxHinv

The approximate Hessian inverse is used to precondition CG.

Methods

findSearchDirection()

findSearchDirection should return an approximation of:
