Webbaseline, which is a centered greedy rollout baseline. Like [11], 2-opt is also considered.As a result, theyreport good results when generalizing to large-scale TSPinstances.Our simpler model and new training method outperforms GPN on both small and larger TSP instances. III. BACKGROUND This section provides the necessary … WebAM network, trained by REINFORCE with a greedy rollout baseline. The results are given in Table 1 and 2. It is interesting that 8 augmentation (i.e., choosing the best out of 8 greedy trajectories) improves the AM result to the similar level achieved by sampling 1280 trajectories.
