Part b
Discuss how to adjust edge weights in the directed multigraph when negative costs are present. Propose a strategy to maintain valid route optimization despite negative edge weights, and explain potential limitations or considerations of your proposed strategy.
Modeling Transportation Networks Using Graph Theory
Consider a city transportation network represented as a directed weighted graph. The network must meet specific regulatory and operational constraints for safety and efficiency.\n\n(a) Formulate the constraints that ensure no intersection (node) has more than 4 incoming roads and at least 2 outgoing roads, while also ensuring the network does not contain cycles that may […]
