[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.

[Other] Johnson DL : 0: Johson算法是目前最高效的在无负环可带负权重的网络中求所有点对最短路径的算法. Johson算法是Bellman-Ford算法, Reweighting(重赋权重)和Dijkstra算法的大综合. 对每个顶点运用Dijkstra算法的时间开销决定了Johnson算法的时间开销. 每次Dijkstra算法(d堆PFS实现)的时间开销是O( E * lgd(V) ). 其中E为边数, V为顶点数, d为采用d路堆实现优先队列ADT. 所以, 此种情况下Johnson算法的时间复杂度是O( V * E * lgd(V) ).-The Johson algorithm is currently the most efficient of the network without negative ring can with negative weights seek all points of the shortest path algorithm.
