So far, there have been many research efforts on the shortest path finding problem. For instance, [A.sup.*] algorithm estimates neighboring nodes using a heuristic function and selects minimum cost node as the closest one to the destination. Pruning method, which is known to outperform the [...
As our second contribution, we add a real-valued parameterβto our pruning algorithm that extends the flexibility of our approach and allows to control the quality of pruning. Specifically, when deciding whether a route shall be pruned, we compare the route distance between two locations to the ...

As pruning literals from a clause can only generalize the concept, i.e., increase the set of covered examples, a post-pruning algorithm has no means for adjusting the second rule to this new situation. Thus, the learner may be lead down a garden path, because the set of examples that ...
Inside the loop, rk(V, F, e) is computed for all edges in each of n iterations, so the total time complexity is O n|E||V |(|E| + |V |) log |V |). Algorithm 2. BF algorithm Input: A weighted graph G = (V, E), q and γ Output: Subgraph H ⊂ G 1: F ← E 2...

Shortest path algorithmsRanking best solutionsWe propose an exact method to solve the constrained shortest path (CSP) problem. The new approach takes advantage of the binary partition strategy of a recent K shortest paths (K-SP) algorithm that allows posing numerous additional path constraints in ...
While discovering shortest path, the algorithm also offers an array of shortest path in ascending order of the path length. However, vehicular traffic exhibits network duality viz. static and dynamic network graphs. Shortest route for static distance graph is pre-computed and stored for look-up, ...
