Speaking of odd things in scipy.optimize ...
I have a problem that is too large for the typical O(N^2) methods, so I
implemented steepest descent and nonlinear conjugate gradient methods.
I wanted to use the function line_search() in optimize.py, but I am
mystified by its use of the zoom() function:
def zoom(a_lo, a_hi):
That looks like an uncompleted stub function to me. Correct?
