StatisticalMechanics.Ensemble

This module provides generic functionality to deal with ensembles in statistical mechanics.

class StateProbability a where

The state probability functions provide conversion from some types a into non-normalized probabilities. For "real" applications, using the logProbability function is preferred. This functions allows for easy abstraction when types a are given as fractions of some actual value (say: deka-cal), or are discretized.

The returned values are not normalized, because we do not now the total evidence Z until integration over all states has happened -- which is not feasible in a number of problems.

TODO replace () with temperature and results with non-normalized P or LogP, depending.

Methods

stateProbability :: () -> a -> ()

Given a temperature and a state "energy", return the corresponding non-normalized probability.
