Replica-Permutation Molecular
Dynamics Simulations :
Better Alternative to ReplicaExchange Method
We proposed a new method for molecular dynamics simulations,
which is referred to as the replica-permutation method (RPM) [1]
to realize more efficient sampling than the replica-exchange
method (REM). In RPM, not only exchanges between two replicas
but also permutations among more than two replicas are
performed.
Furthermore, instead of the Metropolis algorithm, the Suwa−Todo
algorithm is employed for replica-permutation trials to minimize
its rejection ratio. We found that RPM sampled not only
the temperature space but also the conformational space more
efficiently than REM for all systems.
