To evaluate and optimize reinforcement learning algorithms for efficiently finding kinetically feasible chemical reaction pathways across large-scale reaction networks.
Tested reinforcement learning algorithms using a large benchmark dataset of chemical reaction path networks linking reactant and product local minimum structures.
Evaluated search policies based on product energetic and structural similarity, comparing standard baselines (greedy, random, uniform) with exploration-exploitation balanced algorithms including Thompson sampling, probability of improvement, and expected improvement.
Baseline greedy, random, and uniform search policies displayed substantial performance instability across different chemical systems.
Balanced exploration-exploitation policies (Thompson sampling, probability of improvement, and expected improvement) consistently achieved stable, high-efficiency pathway discovery across the benchmark networks.
