Abstract

Despite growing accessibility due to advances in computing power, ligand-protein Relative Binding Free Energy (RBFE) calculation remains a resource-intensive activity, which limits its practical application. Improved computational efficiency via bespoke sampling of the alchemical transformation coordinate, λ, is under-explored. We show here that a simple approach for on-the-fly bespoke λ scheduling, named Adaptive Lambda Scheduling (ALS), yields significant reduction in computational cost whilst retaining predictive performance.
