Networks

Networks are an easy way to set up ensembles for path sampling calculations, and to retain a context for those ensembles when analyzing the results of a simulation.

Many path sampling methods (transition interface sampling as one example) require sampling multiple path ensembles, and then results from those path ensembles are combined in analysis. As such, the path ensemble itself is not enough: you need both the path ensemble and its context. Networks provide that context.

Networks are so named because they allow the study of complicated transition networks, instead of just single transitions. It is at this level that we encounted ideas like multiple state path sampling methods and multiple interface set transition interface sampling.

A longer discussion of networks, and the associated concept of transitions, can be found in the file Transitions and Networks.
