Greedy rollout baseline
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 … WebWe propose a modified REINFORCE algorithm where the greedy rollout baseline is replaced by a local mini-batch baseline based on multiple, possibly non-duplicate sample rollouts. …

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). 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. Table 1: Inference techniques on the AM for TSP Method TSP20 ...
