I am looking for a function that randomly selects a permutation of a sequence. For instance given "1,2,3", it would produce something like "2,1,3" randomly selected from all possible permutations. I could code this myself by creating a container with all possible permutations and randomly selecting one, but this isn't reasonably if the size of the sequence gets larger. I've looked on the web and found an old 4 line FORTRAN subroutine that appears to do this. If boost don't already have this, I will attempt to convert this to C++.
