SimPEG.optimization.InexactGaussNewton.modifySearchDirectionBreak

InexactGaussNewton.modifySearchDirectionBreak(p)

Code is called if modifySearchDirection fails to find a descent direction.

The search direction is passed as input and this function must pass back both a new searchDirection, and if the searchDirection break has been caught.

By default, no additional work is done, and the evalFunction returns a False indicating the break was not caught.

Parameters:

p (numpy.ndarray) – searchDirection

Return type:

tuple

Returns:

(xt, breakCaught) numpy.ndarray, bool
