WebJul 4, 2024 · They trained the model using the REINFORCE algorithm with a greedy rollout baseline and outperformed several TSP and VRP models, including . [ 4 ] and [ 8 ] adapt the model from [ 17 ] to improve the performance on the CVRP and the CVRP-TW respectively by making the feature embeddings more informative. WebThe baseline term reduces gradient variance and increases learning speed while not biasing the gradient [19]. The baseline used here is the greedy rollout baseline [16] which is the cost of a solution from a greedy decoding of the best policy so far.
