Explanation: Find the path with the smallest cost between S-T, that is, the shortest path of a single source. If t is no longer accessed, the algorithm ends. Otherwise, find the minimum residual capacity C based on the shortest path, add the maximum traffic plus C, then update the edge of the shortest path, subtract C from the forward arc, and add c to the reverse arc, and create a reverse billing edge. The minimum

Recently, due to work, you need to learn the relevant knowledge of real estate enterprises. Therefore, sorting out some learning results can be regarded as a result display for your learning actions, and also examining your learning depth, third, I will share my learning experience with you.
The content of the first lesson shows a policy report on low-cost operations of real estate enterprises. Currently, the real estate market is very popular. Many

The problem becomes the maximum cost flow.The process of building the map:Each point I is split into left point I and right point i + N * N. Virtual One super Source point outset = 0, super sink point inset = 2 * n * n + 1.(1) When I is the beginning or the end point, the left point to the right to build the edge, the capacity of the ed

"Using the right features in the correct situation" is a basic standard for competent C + + programmers. To do this, you first need to understand how each feature in the language is implemented and its cost. This paper focuses on several new C + + features that have an impact on efficiency relative to traditional C: compile-time cost runtime overhead Docum
Based on the network maximum flow problem, the minimum cost problem, the cost weight and the capacity limit of maximum flow problem are two concepts, in essence, the problem is to find the weighted shortest path of the graph, but to realize it under the precondition of maximum flow. Therefore, the Bellman-ford algorithm is used to find the augmented path while calculating the minimum
Many companies choose the reason for SEO, is two words: cheap. They think that advertising is always the most expensive, and do not spend a lot of SEO advertising on the internet, as long as hiring a person or a team to do the rankings, you can wait for a steady flow of traffic, and can continue for a long time. But is that really the case? SEO Services is really that cost-effective? Let us take a look at the cost

OSPF is a typical link-State routing protocol. It is generally used in the same routing domain. Here, a routing domain refers to an autonomous system, that is,, it refers to a group of networks that exchange route information through a unified routing policy or routing protocol.
In this AS, all OSPF routers maintain a database that describes the AS structure and stores the status information of the corresponding link in the routing domain, the OSPF router uses this database to calculate its OSPF
Today, applications of the Unified Communication solution are closely related to cloud services, and the relationship between the two is inextricably linked. The implementation of the UC solution of cloud services will significantly change the technical cost indicators.
As voice and video communication are integrated into automated business applications, it will become increasingly dependent on software rather than hardware, which will become especia
