Permutations are ubiquitous in many realworld problems, such as voting, ranking, and data association.Representing uncertainty over permutations is challenging, since there are n! possibilities,
and typical compact and factorized probability distribution representations, such as graphical models,cannot capture the mutual exclusivity constraints associated with permutations.
This toolbox provides some of the key algorithm and examples as decribed in the paper
