In addition, minimize() can handle constraints on the solution to your problem. 2016-11-04 Your code has the following issues: The way you are passing your objective to minimize results in a minimization rather than a maximization of the objective. If you want to maximize objective with minimize you should set the sign parameter to -1.See the maximization example in scipy documentation. minimize assumes that the value returned by a constraint function is greater than zero. The SciPy library provides local search via the minimize() function. The minimize() function takes as input the name of the objective function that is being minimized and the initial point from which to start the search and returns an OptimizeResult that summarizes the success or failure of the search and the details of the solution if found.

minimize (fun, x0, args = (), *, method, tol = None, options = None) [source] ¶ Minimization of scalar function of one or more variables. This API for this function matches SciPy with some minor deviations: Gradients of fun are calculated automatically using JAX’s autodiff support when required. I have a computer vision algorithm I want to tune up using scipy.optimize.minimize. Right now I only want to tune-up two parameters but the number of parameters might eventually grow so I would like to use a technique that can do high-dimensional gradient searches.
