I'm working on a problem where I've got to minimize the following:
$\sum\limits_{i=1}^n(a+c\sqrt{(y_i^2+1)}+dy_i-v_i)^2$
with the following constraints:
$0\leq c \leq 4e$
$|d| \leq c \mbox{ and } |d| \leq 4e-c$
$a \leq c \leq f$
Where $e$ and $f$ are just two constants.
Perhaps I'm doing something quite stupid, but doesn't this yield 6^2 complementary conditions to check?
