simpeg.optimization.SteepestDescent.findSearchDirection#

SteepestDescent.findSearchDirection()[source]#

findSearchDirection should return an approximation of:

$$Hp=-g$$

Where you are solving for the search direction, p

The default is:

$$\begin{array}{r}\begin{array}{c}H=I\\ p=-g\end{array}\end{array}$$

And corresponds to SteepestDescent.

The latest function evaluations are present in:

self.f, self.g, self.H

Return type:

numpy.ndarray

Returns:

p, Search Direction
