Returns the indices of the minimum values along an axis. See also ndarray.argmin , argmax Notes In case of multiple occurrences of the minimum values, Dec 1, 2019 ... I was playing with ArgMin but I'm not sure how to use it for constrained optimization. For example, ArgMin[x^2, x] returns 0 as expected. The global argmin occurs at x = 1. The derivative of the function is not zero at this point. Constrained optimization problems cannot be solved by finding roots.
