WebThe minimize function provides a common interface to unconstrained and constrained minimization algorithms for multivariate scalar functions in scipy.optimize. To demonstrate the minimization function, consider the problem of minimizing the Rosenbrock function of N variables: f(x) = N − 1 ∑ i = 1100(xi + 1 − x2i)2 + (1 − xi)2.
