VRP has been proved to be an NP-hard problem [2], and it becomes even 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.

WebJun 18, 2024 · Reinforcement learning models are a type of state-based models that utilize the markov decision process (MDP). The basic elements of RL include: Episode (rollout): playing out the whole sequence of state and action until reaching the terminate state; Current state s (or st): where the agent is current at; Weba deterministic greedy roll-out to train the model using REINFORCE (Williams 1992). The work in (Kwon et al. 2024) further exploits the symmetries of TSP solutions, from which diverse roll-outs can be derived so that a more effi-cient baseline than (Kool, Van Hoof, and Welling 2024) can be obtained.

WebThe policy. a = argmax_ {a in A} Q (s, a) is deterministic. While doing Q-learning, you use something like epsilon-greedy for exploration.
