# Constant-pressure Monte Carlo

In **constant-pressure Monte Carlo** a trial change in the volume becomes one of the Monte Carlo moves.
The weighting function, *w*, is given by (Eq. 2 in ^{[1]})

for a change in volume, , one has

If then the move is accepted, and if then *r* is compared with a random number
. If then the move is accepted.
