[graph] The getAllPathsBetween method in the [graph] provides a 'limit' parameter to control this exponential time complexity method from entering into a deadlock state. The getMinPathsBetween method, by default, calls the Dijkstra method to avoid invoking the excessively high time complexity method, getAllPathsBetween.
