13. The method of claim 11 , wherein a path weight is computed for each candidate path among the candidate paths as a sum of the arc weight associated with each of the arcs of the candidate path.
13. The method of claim 11 , wherein a path weight is computed for each candidate path among the candidate paths as a sum of the arc weight associated with each of the arcs of the candidate path. 15. The method of claim 13 , wherein a probability of the candidate path being the most probable path is directly related to the path weight of the candidate path, and wherein selecting the most probable path further comprises selecting the candidate path having the path weight that is highest as the most probable path.
