[Other] Floyd-Warshall-c-chengxi 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. Johson algorithm Bellman-Ford algorithm Reweighting (re-empower the weight) and Dijkstra algorithm for the large integrated. For eachtime overhead of the vertices using Dijkstra algorithm to determine the time of the Johnson algorithm overhead each Dijkstra algorithm (d-heap PFS), time overhead is O (E* lgd (V)) where E is the number of edges, V verticesd d Lu heap priority queue the ADT. this case the Johnson algorithm time complexity is O (V* E* lgd (V)).

[Other] floyd-knapsack DL : 0: floyd knapsack Floyd-Warshall算法（Floyd-Warshall algorithm）是解决任意两点间的最短路径的一种算法，可以正确处理有向图或负权的最短路径问题，同时也被用于计算有向图的传递闭包。Floyd-Warshall算法的时间复杂度为O(N3)，空间复杂度为O(N2)。背包问题(Knapsack problem)是一种组合优化的NP完全问题。问题可以描述为：给定一组物品，每种物品都有自己的重量和价格，在限定的总重量内，我们如何选择，才能使得物品的总价格最高。问题的名称来源于如何选择最合适的物品放置于给定背包中。-floyd knapsack Floyd-Warshall algorithm (Floyd-Warshall algorithm) is an algorithm to solve the shortest path between any two points can correctly handle have the shortest path to the map or negative weights, but also be used to calculate the transitive closure of a directed graph package. Floyd-Warshall time complexity of the algorithm is O (N3), space complexity is O (N2). Knapsack problem (Knapsack problem) is NP-complete optimization of a composition. The problem can be described as follows: given a set of items, each item has its own weight and price, for a limited total weight, how we choose to make the total price of the most goods. The name comes the question of how to choose the most suitable place objects in a given backpack.

[Other] dist DL : 0: 用最短路径算法算出特定两点之间的距离输入：直接读取net.in文件第一行为四个整数N,M,S,T,每两个整数之间用一个空格隔开，分别表示网络的节点（编号为1到N），网络线段数，以及起点终点编号接下来M行，每行三个整数U,V,D，每个整数之间用空格隔开，表示节点U和V之间有一条线路相连，距离是D，（两个节点可能有多条线路）输出：直接写入到net.out文件，输出只有一行，表示从S点到T点的最短距离（如果不通则输出-1）（N<=100，M<=N*N,D<=1000）(Use the shortest path algorithm to calculate the distance between two specific two points Input: read the net.in file directly The first behavior is four integers N, M, S and T. Every two integers are separated by a space, representing the node of the network (number 1 to N), the number of network segments, and the origin and destination number. Next, M row, each row three integers U, V, D, each integer is separated by spaces, indicating that there is a line between nodes U and V, the distance is D, (there may be multiple lines in two nodes). Output: write directly to net.out file, output only one line, which indicates the shortest distance from S point to T point (if it doesn't connect, output -1) (N<=100, M<=N*N, D<=1000).
