Grand canonical Monte Carlo (GCMC) is a simulation technique which avoids this issue by attempting the direct insertion and deletion of water molecules. GCMC is, however, hampered by low acceptance probabilities for insertions in congested systems. To address
WebSep 21, 2024 · In this paper, we present an advancement of FEP that augments MD with grand canonical Monte Carlo (GCMC), an enhanced sampling method, to overcome the problem of sampling water. We accomplished this without degrading computational performance.
