Clone Graph :
Similarly, for the copy of the graph, you must find a way to map the nodes in the new diagram, to quickly locate the address of the new node, so that the new node points to the new node. The map map is used here. Consider that the label of the graph node may be duplicated (the subjec

Dijkstra algorithm solves the single-source shortest path with weights on Directed Graph G = (V, E), but requires that the weights of all edges be non-negative.
Dijkstra is a good example of greedy algorithms. Set a vertex set
The direction of the graph in if between two points can reach each other, it is said that the two points strong connectivity, if all points within a point set can reach each other, then the point set is a strong connected component of the graph, and we need to find all the strongly connected components of the graph, so the Tarjan algorithm to strong connectivity,

Brief introduction
It takes a long time to use the TensorFlow training depth neural network model, because the parallel computing provides an important way to improve the running speed. TensorFlow provides a variety of ways to run the program in parallel, and the questions to consider when using these methods are whether the selected computing device is CPU or GPU, how many cores of each CPU are

Question: poj 2553 the bottom of a graph
Question: the general meaning of this question is to give a directed graph, which requires a point with a degree of 0 after a strongly connected contraction point.
Analysis: Getting started Question: first,
In the compiler, after lexical analysis and grammar analysis, the syntax tree is generated, and in the further processing of the syntax tree, a data structure called a "direction-free graph" is used.
What is a forward-free loop diagram
1, first it is a graph, and then it is a direction graph, followed by any vertex of this direction
Solution report
Question:
N people, m vehicles, coordinates of people and vehicles, and the speed of people, and the minimum time for all people to get on the bus. (A car can only be one person)
Ideas:
The original thought that the minimum time in the bipartite graph became the best match for the bipartite graph. In fact, the time can be divided into two parts to meet the time of the person and the car line
This program is implemented with the graph's adjacent hands. If you want to implement the DFS algorithm using the graph's adjacent linked list, you only need to change the firstadj (), nextadj (), and graph creation operations in this program to the adjacent linked list, you do not need to modify other DFS main program frameworks.

Dijkstra algorithm solves the single-source shortest path with weights on Directed Graph G = (V, E), but requires that the weights of all edges be non-negative.
Dijkstra is a good example of greedy algorithms. Set a vertex set S. the weights of the final shortest path from the source point S to the vertex s in the set are determined. The algorithm repeatedly selects vertex u with Shortest Path estimation, and adds u to S

thought: Figure G is a non-weighted undirected connectivity graph. The length of an edge is counted as 1, so the shortest path to the vertex u and Vertex v is the vertex sequence with the least number of sides of vertex u and Vertex v. Using the breadth-first traversal algorithm, the breadth traversal from U is similar to a layer-by-layer outward expansion from the vertex u, and when the vertex v is first found, the queue includes the recent path from
