Vehicle routing problems (VRPs) are a class of combinatorial problems with wide practical applications. While previous heuristic or learning-based works achieve decent solutions on small problem instances of up to 100 customers, their performance does not scale to large problems. This article presents a novel learningaugmented local search algorithm to solve large-scale VRP. The method iteratively improves the solution by identifying appropriate subproblems and delegating their improvement to a… Expand

Reinforcement Learning for Solving the Vehicle Routing Problem
TLDR
This work presents an end-to-end framework for solving the Vehicle Routing Problem (VRP) using reinforcement learning, and demonstrates how this approach can handle problems with split delivery and explore the effect of such deliveries on the solution quality. Expand
A Learning-based Iterative Method for Solving Vehicle Routing Problems
TLDR

Efficiently solving very large-scale routing problems
TLDR
This paper explores how to design a local search heuristic that computes good solutions for very large-scale instances of the capacitated vehicle routing problem in a reasonable computational time and introduces a new set of benchmark instances that contain up to 30,000 customers and use the heuristic to solve them.

Attention, Learn to Solve Routing Problems!
TLDR
A model based on attention layers with benefits over the Pointer Network is proposed and it is shown how to train this model using REINFORCE with a simple baseline based on a deterministic greedy rollout, which is more efficient than using a value function. Expand

Using Constraint Programming and Local Search Methods to Solve Vehicle Routing Problems
TLDR
This work uses a local search method that is analogous to the shuffling technique of job-shop scheduling, and so meshes well with constraint programming technology, to solve vehicle routing problems. Expand
2-Path Cuts for the Vehicle Routing Problem with Time Windows
TLDR
A strong valid inequality, the 2-path cut, is introduced to produce better lower bounds for the vehicle routing problem with time windows and an effective separation algorithm to find such inequalities is developed. Expand
A sweep-based algorithm for the fleet size and mix vehicle routing problem
TLDR
