what would you think are good exchange rates between the replicas in a
REMD?
:-) I'm about to submit a paper partly on this topic... the short answer
is that most people publishing REMD exchange rates have one that is a
good deal lower. There's literature that recommends 20%, but a lot of
people are in the 10-30% range. If you get rates that seem too low, then
the first thought is to decrease the period between exchange attempts in
order to increase the exchange rate per unit simulation time, but
there's published data (e.g. from Periole & Mark, J. Chem. Phys this
year) that indicates that there are lower limits below which this is
ineffective.
