Greedy rollout baseline
Webthe model is trained by the REINFORCE algorithm with a deterministic greedy rollout baseline. For the second category, in [16], the graph convolutional network [17,18]is trained to estimate the likelihood, for each node in the instance, of whether this node is part of the optimal solution. In addition, the tree search is used to WebTL;DR: Attention based model trained with REINFORCE with greedy rollout baseline to learn heuristics with competitive results on TSP and other routing problems.
