This function can handle multivariate inputs and outputs and has more complicated optimization algorithms to be able to handle this. 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.

Tools used: Pyt 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.

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.
