Vehicle Routing Problem Using Reinforcement Learning: Recent

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.

Attention, Learn to Solve Routing Problems! OpenReview

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 Title: Selecting Robust Features for Machine Learning Applications using … 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 population of kc ks
