We introduce a general framework for adaptive resetting, where stochastic resetting depends on the state and age of the process. Using a reweighting scheme applied to trajectories without resetting, we efficiently compute key observables like first-passage times and steady-states. This enables the design of informed search strategies and complex non-equilibrium behaviors without brute-force sampling. We further develop a machine learning approach to optimize adaptive resetting protocols and demonstrate its effectiveness in accelerating molecular dynamics simulations.

We introduce informed stochastic resetting, a novel strategy for enhancing molecular dynamics simulations by selectively resetting only when the reaction coordinate indicates insufficient progress. Applied to a model system and chignolin in explicit water, this approach accelerates Metadynamics simulations by 2–3 orders of magnitude. By leveraging information about reaction progress, informed resetting significantly extends the applicability of stochastic resetting for overcoming time scale limitations in molecular simulations.

​

Machine learning models have become indispensable tools in applications across the physical sciences. However, their training is often time-consuming. Several protocols have been developed to perturb the learning process and improve the training. However, their design is usually done ad hoc by intuition and trial and error. To rationally optimize training protocols, we frame them as first-passage processes. This reveals that a model’s response at a single perturbation frequency can predict its behavior across others.

We derive high-order Michaelis-Menten equations that extend the classical linear relation between mean turnover time and reciprocal substrate concentration. These equations reveal universal linear relations for higher-order moments, granting access to previously inaccessible kinetic parameters. We show how key observables—such as the enzyme-substrate lifetime, the binding rate, and the probability of successful catalysis—can all be inferred from these relations.

We introduce smart resetting—a strategy that leverages information to selectively reset a diffusing particle only when it benefits its progress toward a target. Our analysis demonstrates that smart resetting consistently lowers the energy cost per mean first passage time compared to regular resetting, achieving the known minimum energy cost bound for a diffusing particle regardless of the resetting rate. We extend our findings to consider nonlinear energetic cost functions and drift-diffusion processes, offering deeper insights into the interplay between information and resetting.
