[AI-NN-PR] MINIMALpATH DL : 0: A shortest path tree, in graph theory, is a subgraph of a given (possibly weighted) graph constructed so that the distance between a selected root node and all other nodes is minimal. It is a tree because if there are two paths between the root node and some vertex v (i.e. a cycle), we can delete the last edge of the longer path without increasing the distance from the root node to any node in the subgraph. If every pair of nodes in the graph has a unique shortest path between them, then the shortest path tree is unique. This is because if a particular path from the root to some vertex is minimal, then any part of that path (from node u to node v) is a minimal path between these two nodes. In graphs with no negative distances, Dijkstra s algorithm computes the shortest path tree, from a given vertex. In graphs with possibly negative distances, the Bellman-Ford algorithm can be used instead.

[Mathimatics-Numerical algorithms] Warshalls-Transitive-Closure DL : 0: In computer science, the Floyd–Warshall algorithm (also known as Floyd s algorithm, Roy–Warshall algorithm, Roy–Floyd algorithm, or the WFI algorithm[clarification needed]) is a graph analysis algorithm for finding shortest paths in a weighted graph (with positive or negative edge weights).

[SCM] ns2 DL : 0: Many interesting route planning problems can be solved by computing shortest paths in a suitably modeled, weighted graph representing a transportation network. Such networks are naturally road networks or timetable networks of public transportation. For large networks, the classical Dijkstra algorithm to compute shortest paths is too slow. And therefore have faster algorithms been developed in recent years. These new algorithms have in common that they use precomputation and store auxiliary data to speedup subsequent shortest-path queries.
