appears behind VI in the sort. Because of this feature, topological sequencing is not possible if the graph contains loops.A simple way to find a topological sorting algorithm: Select a vertex without an edge, display the point, delete it along with its edges, and then apply the same method to the rest of the diagram.The so-called penetration (indegree) refers to the number of edges (u,v) of the vertex v. Assuming that the degree of each vertex is stored and the graph is read into an adjacency
city,
The side represents the distance between two cities, when there are N cities, there may be N (n-1)/2 edge, then how to choose (n-1) edge to make the total distance between the city is the smallest, in fact it
The abstract model is to find the "minimum spanning tree" problem.
3. Prim algorithm
Of course how to seek the "minimum spanning tree" problem, predecessors have been summed up for us, we just divert is,
The first step: we build the set "V,u", all the vertices in the graph are p

For many enterprise users, performance is not the primary factor for server selection. The most important indicator is low power consumption and capital budget. AMD's latest haolong 4100 series processor is developed and designed for such users. The 4100 series is a low-level version of The Magny-Cours codenamed mainiku core haolong 6100 series processor. Haolong 6100 has two versions: 8-core and 12-core. In contrast, the "Lisbon" haolong processor is only a single core.

Problem description:
In a connected graph G with several vertices, if the subgraph G' contains all vertices and some edges in G and does not form a loop, G' is called the Spanning Tree of graph G, the spanning tree with the minimum cost is called the least spanning tree. For example, if G is set, find the edge connecting all vertices (V1, V2, V3, V4, V5, V6) of graph G, and the sum of the weights of these edges is the minimum. How can we generate the

better than Windows NT + IIS to run ASP, while Apache is slightly more dominant. The existing version can process more than 10000 operations (one request is one operation) within one second on a high-performance host ). Therefore, enterprises select the appropriate software platform and hardware based on application development requirements.
At present, computer development is very fast, and mainstream Xeon multi-core technologies can meet the need
