A hierarchical anisometric positional encoding that combines distance-indexed in-route and depot-anchored angular cross-route components improves transformer-based solvers for vehicle routing problems over index-based alternatives.
12 B MDP Formulation We model deconstruction as a Markov Decision Process (MDP) in which a policy iteratively removes customers from a feasible solution to reduce total travel cost
