However, in the work of Stoustrup and co-workers, it was described how a class of such problems could be turned into convex optimization problems, and explicit algorithms for efficient solutions were suggested.
I arbejdet af Stoustrup og hans medarbejdere, bliver det imidlertid beskrevet hvorledes en klasse af denne type af problemer kan omskrives til konvekse optimeringsproblemer, og eksplicitte algoritmer for løsningen af disse blev foreslået.
