Markov

Three type classes for deterministically analyzing Markov chains with known parameters. Markov0 is intended to list possible outcomes, Markov should allow for more sophisticated analysis. A more general definition can be found in Markov.Generic that allows for containers other than lists. See Markov.Example for examples. See README for a detailed description.

Combine

class Combine a where

Within equivalence classes, combine should be associative, commutative, and idempotent (up to equivalence). I.e. if x == y == z,

(x `combine` y) `combine` z = x `combine` (y `combine` z)

x `combine` y = y `combine` x

x `combine` x == x
