Description: Ford algorithms trees
The Bellman–Ford algorithm computes single-source shortest paths in a weighted digraph. For graphs with only non-negative edge weights, the faster Dijkstra s algorithm also solves the problem. Thus, Bellman–Ford is used primarily for graphs with negative edge weights. The algorithm is named after its developers, Richard Bellman and Lester Ford, Jr.

Description: 这个例程,会在多条相同最短路径中选出边数最少的路径.只是改变path域即可在遍历的时候访问到边数少的路径.核心的思想,就是建立一个数组,存放从出发点到当前顶点的最短路径边数.通过每次查看最短路径相同的情况, 即dv + cvw = dw.时,如果 Count[v] + 1 < Count[w]时,就执行 Count[w] = Count[v] + 1, 同时 w -> path = c.-This routine will be the same number of shortest paths in the selected path with the least number of edges. Just change the path traversal time domain can be accessed in the number of edges in the path less. The core idea is to create an array to store the starting point from The current number of edges in the shortest path vertices. by the shortest path each time you view the same situation, that is, dv+ cvw = dw., if Count [v]+ 1 < Count [w] when, on the implementation Count [w] = Count [ v]+ 1, while w-> path = c.

Description: 本文在脉冲耦合神经网络(PCNN2Pulse Coupled Neural Network) 的基础上,提出了时延脉冲耦合神经网络
(DPCNN2Delay PCNN) ,并将其成功地用于求解最短路径,同时给出了基于DPCNN 的最短路径求解算法. Caulfield 与
Kinser 提出了用PCNN 求解迷宫问题的方法,虽然他们的方法也可用于求解最短路径,但所需神经元的数量巨大,而本
文的方法所需的神经元的数量远小于他们的方法. 同时,本文的方法充分利用了DPCNN 脉冲快速并行传播的特点,可
迅速地求出最短路径,其所需的计算量仅正比于最短路径的长度,与路径图的复杂程度及路径图中的通路总数无关.
计算机仿真结果表明,采用本文的方法,用少量的神经元就可迅速地求出最短路径.- This paper presents DPCNN(Delay Pulse Coupled Neural Network) based on PCNN and uses DPCNN to find the
shortest path successfully.Meanwhile ,the algorithmof finding the shortest path based on DPCNN is described. Caulfield and Kinser in2
troduced the PCNN method to solve the maze problem and although their method also can be used to find the shortest path ,a large
quantity of neurons are needed. However ,the approach proposed in this paper needed very fewer neurons than proposed by Caulfield
and Kinser. In the meantime ,due to the pulse parallel transmission characteristic of DPCNN ,the approach proposed can find the short2
est path quickly. The computational complexity of our approach is only related to the length of the shortest path , and independent to
the path graph complexity and the number of existing paths in the graph. The results of computer simulations show that by using the
approach proposed in this paper ,we can use a small quantity of neurons to find the shortest p

Description: For a given source vertex (node) in the graph, the algorithm finds the path with lowest cost (i.e. the shortest path) between that vertex and every other vertex. It can also be used for finding costs of shortest paths from a single vertex to a single destination vertex by stopping the algorithm once the shortest path to the destination vertex has been determined. For example, if the vertices of the graph represent cities and edge path costs represent driving distances between pairs of cities connected by a direct road, Dijkstra s algorithm can be used to find the shortest route between one city and all other cities. As a result, the shortest path first is widely used in network routing protocols, most notably IS-IS and OSPF (Open Shortest Path First).-For a given source vertex (node) in the graph, the algorithm finds the path with lowest cost (i.e. the shortest path) between that vertex and every other vertex.

Description: 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.
