We present some reoptimization techniques for computing (shortest) hyperpath weights in a directed hypergraph.These techniques are exploited to improve the worst-case computational complexity (as well as the practical performance) of an algorithm finding the K shortest hyperpaths in acyclic hypergraphs.
