Time Complexity
$O(kn + {1.2852}^k)$
Space Complexity
$O(k^{3})$ auxiliary? (potentially $O(k^{2})$??) words
(First auxiliary graph contains O(k^2) edges; algorithm subsequently branches to a depth of O(k) (each fork being degree O(1)), with a new O(k^2)-sized graph at each depth. Interleaving shouldn't increase space usage asymptotically. (Could possibly be reduced to O(k) by just keeping track of graph deltas?) (but also a different source claims exponential?))
