It implements several methods for sequential model-based optimization. skopt aims to be accessible and easy to use in many contexts. The library is built on top of NumPy, SciPy and Scikit-Learn. I have a computer vision algorithm I want to tune up using scipy.optimize.minimize.

As all optimization-algorithms within scipy.minimize are quite general, there will always be faster methods, gaining performance from special characteristics of your problem. It will be a trade-off, how much analysis and work is done to gain performance. def minimize(self, x: numpy.ndarray): """ Apply ``scipy.optimize.minimize`` to a single point. Args: x: Array representing a single point of the function to be minimized.

Least-squares minimization and curve f We can use scipy.optimize.minimize() function to minimize the function.

The method wraps the SLSQP Optimization subroutine originally implemented by Dieter Kraft [12] . Method SLSQP uses Sequential Least SQuares Programming to minimize a function of several variables with any combination of bounds, equality and inequality constraints. The method wraps the SLSQP Optimization subroutine originally implemented by Dieter Kraft [12] . For documentation for the rest of the parameters, see scipy.optimize.minimize. Options disp bool. Set to True to print convergence messages. maxiter, maxfev int.

wrap-up; reference; scipy를 이용한 optimization. 제가 공부한 포스트에서는 import scipy as sp로 importing한 다음 scipy를 이용하는데, 요즘에는 이게 막혀 있는 것 같아요. 묘하게도 반드시 from scipy.optimize import minimize와 같은 방식으로 사용해야 minimize(method='trust-constr')¶.
