The penalty function method
WebbYou calculated the gradient wrong (outside valid domain). Check your derivative of the penalty function. The partial derivative of max ( x 1 2 + x 2 2 − 1, 0) 2 wrt x 1 is not 4 x 1 3. Rather, it should be 4 x 1 ( x 1 2 + x 2 2 − 1) (when outside the valid domain).

A common choice is a quadratic penalty such as p (x) = max (0, g (x) ) 2 .
