Greedy rollout baseline
Webrobust baseline based on a deterministic (greedy) rollout of the best policy found during training. We significantly improve over state-of-the-art re-sults for learning algorithms for the 2D Euclidean TSP, reducing the optimality gap for a single tour construction by more than 75% (to 0:33%) and 50% (to 2:28%) for instances with 20 and 50 WebWe contribute in both directions: we propose a model based on attention layers with benefits over the Pointer Network and we show how to train this model using REINFORCE with a simple baseline based on a deterministic greedy rollout, which we find is more efficient than using a value function.
