Modern networks run "middleboxes" that offer services ranging from network address translation and server load balancing to firewalls, encryption, and compression. In an industry trend known as Network Functions Virtualization (NFV), these middleboxes run as virtual machines on any … Webrouting problem. The path flow formulation contains a dual variable ωij for each link and another dual variable σk for each commodity k = 1…K. We define the reduced cost as k i j P ij σω = ck P + ∑ω −σ ( ,)∈, cP The path flow complementary slack conditions are stated in Ahuja et al [7] and are valid at optimality. [ δ (P)f(P) u ...
Web20 iun. 2024 · This paper proposes a two-commodity flow formulation for the MDVRP considering a heterogeneous vehicle fleet and maximum routing time. Its computational performance is compared to a traditional formulation, the so called three-index formulation, which is adapted to fit the same problem.
