Scipy optimize minimize

The goal of this exercise is to fit a model to some data. 2020-06-21 · Optimization deals with selecting the best option among a number of possible choices that are feasible or don't violate constraints. Python can be used to optimize parameters in a model to best fit data, increase profitability of a potential engineering design, or meet some other type of objective that can be described mathematically with variables and equations. Algorithmic Portfolio Optimization in Python.
