Deterministic greedy rollout
Webthis model using REINFORCE with a simple baseline based on a deterministic greedy rollout, which we find is more efficient than using a value function. We significantly improve over recent learned heuristics for the Travelling Salesman Problem (TSP), getting close to optimal results for problems up to 100 nodes. WebDec 13, 2024 · greedy rollout to train the model. With this model, close to optimal results could be achieved for several classical combinatorial optimization problems, including the TSP , VRP , orienteering

WebMar 22, 2024 · We propose a framework for solving combinatorial optimization problems of which the output can be represented as a sequence of input elements. As an alternative to the Pointer Network, we parameterize a policy by a model based entirely on (graph) attention layers, and train it efficiently using REINFORCE with a simple and robust … Webrobust baseline based on a deterministic (greedy) rollout of the best policy found during training.

While doing Q-learning, you use something like epsilon-greedy for exploration. However, at "test time", you do not take epsilon-greedy actions anymore. "Q learning is deterministic" is not the right way to express this. One should say "the policy produced by Q-learning is deterministic ...
