I'm working on a convex quadratic separable min-cost flow problem with the following structure:
$P = \{\frac{1}{2}x^tQx + qx : Ex = b, 0 \leq x \leq u\}$$P = \{\min \frac{1}{2}x^tQx + qx : Ex = b, 0 \leq x \leq u\}$
But I'm stuck on deriving the KKT conditions to solve the problem.
Can someone help me with the computation?
