Derivative-free optimization python
WebI would suggest that you take a look at the derivatives, at least in a few points in your parameter space. Compute them using finite differences and the default step size of SciPy's fmin_l_bfgs_b, 1e-8. Here is an example of how you could compute the derivates. Try also plotting your target function.
