Fair collaborative vehicle routing: A deep multi-agent reinforcement learning approach

no code implementations26 Oct 2023 Stephen Mak, Liming Xu, Tim Pearce, Michael Ostroumov, Alexandra Brintrup

Our contribution is that we are the first to consider both the route allocation problem and gain sharing problem simultaneously - without access to the expensive characteristic function.
