Simplex method minimize
WebbThe 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.

Webb10 apr. 2024 · There is a method of solving a minimization problem using the simplex method where you just need to multiply the objective function by -ve sign and then solve it using the simplex method. All you need to do is to multiply the max value found again by -ve sign to get the required max value of the original minimization problem. http://seas.ucla.edu/~vandenbe/ee236a/lectures/simplex.pdf
