You should not change a question so as to invalidate such a valid answer. After your edit, your new question is completely different from the original one, even with the vector $\boldsymbol{\alpha}$ replaced by a scalar $\alpha$, and a quadratic restriction instead of the original affine one. Therefore, I suggest you restore your original post and finalize this matter. Then you may want to post your new question separately, possibly not on MathOverflow. | |
