....length of the shortest path from every node to t is computed; then these values are used as an exact estimation of the best way to complete a partial path starting at s. In practice, this improvement dramatically speeds up Shier s algorithm, but the computational complexity remains quadratic in K [SK87, SK89, MC91]. A new algorithm for the generation of the K Best Sentence Hypotheses for a given utterance was recently proposed by the authors in the field of Automatic Speech Recognition [JM92, JMV93] In this paper, we present this algorithm as a general procedure for the K shortest paths problem, and ....
