The shortest path problem is one of the most studied problem in graph theory and operations research. A classic generalization of this problem is the problem of finding k shortest simple paths (kSSP for short). That is, the problem of finding a shortest, a second-shortest, etc. until a k-th shortest simple path from a source to a destination in a directed weighted graph. Yen (1971) proposed the state-of-the-art kSSP algorithm, with theoretical time complexity in O(kn(m+n \log{n})), where n is the number of vertices and m is the number of arcs of the input digraph. Since then, the problem has been widely studied from an algorithmic engineering perspective, that is designing exact algorithms offering better performances in practice.In this th...
