Original The Hubble telescope was launched to space by NASA in April, 1990 at a cost of over a billion dollars. Right from the start there is trouble with the Hubble. The pictures it sent us were very disappointing because its main mirror was faulty! NASA is now going to put the telescope right, so it'll soon be sending up four astronauts to repair it. The shuttle Endeavor would be taking the astronauts to

Question:King Arthur wants to hold a knight meeting on the round-table. In order not to cause conflicts between the knights, but to make the topics of the meeting have satisfactory results, before each meeting, you must have the following
Timestamp Dfs_clock: It's plain to note that the order in which each node is accessed is recorded. Suppose we use the pre to save, then if Pre[u] > Pre[v], then we can know the first to access the V, after access to U.Now given an edge, (U, v), and the ancestor of U is FA, if there is pre[v] 1 to find the connected component:A mutually accessible node is called a connected component;#include 2 cutting top a

Compared to the algorithm used to calculate the nodes for an undirected graph, the algorithm only has one more stack to store all the edges without any nodes. When the nodes are shut down, all the edges are popped up for storage.

Original address: 77431043First, explainIn the graph G, if there is at least one mutually accessible path between the two vertices, the two vertices are strongly connected (strongly connected). If there is strong connectivity to every two vertices of the graph G, the G is a strongly connected graph. The strongly connected

Detailed explanations and differences between Left-connected and right-connected MYSQL and internal-connected mysql
Difference between left and right connections and internal connections of MYSQLHere, we will go through an example to explain these concepts clearly.
The Code is as follows:
drop table table1;CREATE TABLE `andrew`.`table1`(`name` VARCHAR(32) NOT NUL
Definition:For a connected graph, if any two points have at least two points do not repeat the path, it is said that the graph is a point double-connected (for short), if any two points there is at least two edges do not repeat the path, it is said that the graph is the edge of the two-connected . The definition of a point double

At first, I believe that every one will feel a bit puzzled, mainly because the word "weight", of course, if only to understand and use the two terms, you do not have to care about this irrelevant word.
Well, it's time to talk. The so-called double connectivity and strong connectivity, the biggest difference, but also the most essential difference is that the former applies to undirected graphs, while the latter applies to the undirected graph. The concept of the two is the same, that is, a point

The main effect of the topic:
Give a picture, ask at least how many edges, turn him into a side-connected graph
Topic Analysis:
First, the point of double connected graph is reduced, (the point-connected graph must be a side-connected graph), then get a tree, for a tree, we just need
Topic:find the connected features of a non-graph summaryPlease find out the number of connected features in the graph.Each node in the diagram contains 1 tags and a list of its neighbors. (a linked node (or node) of a non-graph is a sub-graph where any two vertices are connected by a path and are not connected to other
Test instructions: To give you a diagram, ask the maximum number of edges can be added so that the graph is still not strong connected graph, if the original image is strongly connected output '-1 ' analysis: The first to find out the connected components of the indentation, because it is the most added edge, so can be seen as two parts x, Y, only part of the oth

Idea: there is a problem here. By default, strong connectivity is required for graph connectivity. The simplest method is to delete an edge each time and determine whether the graph
