WebAttention, Learn to Solve Routing Problems! Attention based model for learning to solve the Travelling Salesman Problem (TSP) and the Vehicle Routing Problem (VRP), Orienteering Problem (OP) and (Stochastic) Prize Collecting TSP (PCTSP). Training with REINFORCE with greedy rollout baseline. WebGreedy rollout baseline in Attention, Learn to Solve Routing Problems! shows promising results. How to do it. The easiest (not the cleanest) way to implement it is to create a agents/baseline_trainer.py file with two instances (env and env_baseline) of environment and agents (agent and agent_baseline).
