Hi Everyone!
I am looking for a simple way to get a few search directions (e.g., LBFGS, Truncated-Newton) from Scipy. I don't need the full method, just a single search direction. I was thinking about calling directly scipy.optimize.minimize with the parameter maxiter=1
and obtain the direction by difference with the actual point, but I
guess I will obtain a direction scaled by the step size in that case,
right?
Thanks in advance for the help!
