@Deprecated public class KShortestPaths<V,E> extends Object implements KShortestPathAlgorithm<V,E>
The algorithm is a variant of the BellmanFord algorithm but instead of only storing the best path it stores the "k" best paths at each pass, yielding a complexity of $O(k \cdot n \cdot (m^2))$ where $m$ is the number of edges and $n$ is the number of vertices.
