I used the bounding box as a rough approximation to the real constraints. Hopefully the minimum does not land up in the empty quarter.

[$]x^2 + y^2 - 2 = 0[$] is circle radius 2
[$]x=\sqrt{2}\cos\theta[$] and [$]y=\sqrt{2}\sin\theta[$]
[$]x+y=\sqrt{2}(\cos\theta+\sin\theta)=2\sin(\theta+\pi/4)[$]
answer is -2
