Replica-exchange molecular dynamics (REMD) [1] is a tempering method. In this method several replicas of the system are simulated at different temperatures. Every once in a while copies of the system are exchanged.

Thermostats[edit]

It has recently been pointed pointed out that one should be very careful which thermostat one employs, the wrong choice leading to non-ergodic behaviour [2]. One should use a canonical ensemble thermostat [3].
