The np.argmax function by default works along the flattened array, unless you specify an axis. To see what is happening you can use flatten explicitly. 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. Two tolerances can be configured, which are both needed in the stopping criteria. One is a tolerance on the gradient (set with with_tolerance_grad ): If the ... Jul 2, 2016 ...
