WebApr 12, 2012 · 1 Answer. Your variant is NP-hard by a reduction from, e.g., the 3-partition problem where all values are strictly between B/4 and B/2. It might be "solved" using some of the same methods as capacitated vehicle routing. You have to understand, though, that CPP is less a real problem than an excuse to study T-joins. WebAug 2, 2013 · Given a network, the well-known Chinese Postman Problem (CPP) is to find a shortest postman tour traversing each arc of the network at least once and returning to the depot where the postman started.
