SimPEG.optimization.SteepestDescent.findSearchDirection#
- SteepestDescent.findSearchDirection()[source]#
findSearchDirection should return an approximation of:
\[H p = - g\]Where you are solving for the search direction, p
The default is:
\[ \begin{align}\begin{aligned}H = I\\p = - g\end{aligned}\end{align} \]And corresponds to SteepestDescent.
