New stochastic policies enhance molecular simulation path sampling

Researchers have developed two new stochastic control policies, FS-TPS and LaS-TPS, to improve the robustness and efficiency of transition path sampling (TPS) in molecular dynamics simulations. These methods aim to generate more physically plausible rare molecular transition trajectories by learning control forces during explicit simulations. Extensive experiments on alanine dipeptide, chignolin, and BBL protein systems demonstrated that the stochastic policies consistently enhance transition success and path quality while significantly reducing sensitivity to initial conditions compared to deterministic baselines.
