openpathsampling.pathmover.RandomChoiceMover

class openpathsampling.pathmover.RandomChoiceMover(movers, weights=None)

Chooses a random mover from its movers list, and runs that move. Returns the number of samples the submove return.

For example, this would be used to select a specific replica exchange such that each replica exchange is its own move, and which swap is selected at random.

movers

the PathMovers to choose from

Type:

list of PathMover

weights

the relative weight of each PathMover (does not need to be normalized)

Type:

list of floats
