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

, and a on the left, change to a*2, the capacity is 1, because only one time, the cost is the length. Of course you need to reverse the side!

Two test instructions is the same, the data card is not the same!!!Test instructions: give you a n*n matrix, each element represents the weight of the place. Requires that each point can only walk once, the upper-left and lower-right corner can walk two times but the weight of the value can only be obtained once. Ask you to go from the upper left corner to the lower right corner (can only move down

Test instructionsThere are n cities, M to the road, from city 1th to transport K cargo to City N.Each has a direction to the road And each road to transport a maximum number of CI goods, the minimum cost.Analysis:Split the edge, each side split into a cost of a, 3a, 5a edge, so that the cost of each side and the flow of the square is proportional to.Since a maximum of K goods are transported, a source point

Hdu1385Minimum Transport Cost (short-circuit variant)Idea: The most short-circuit variant of the output path .. This question lies in multiple groups of inquiries, so I personally think it is more secure to use floyd. In addition, there is a toll in every city, so you can change the Loose Condition in floyd .. What about the output path ?? I use the successor of the output starting point instead of the precursor to the end point .. Because we care abo

The title probably said, to a picture, delete some one-way edge, so that the starting point s out of the degree of more than 1, the end point T into the degree of more than 1, other points out of the degree equal to the degree. Where the cost of removing the edge is bi, the cost of preserving the edge is AI, and the minimum cost of asking for completion is how mu

For the minimum cost flow, the basic idea and the maximum flow are similar, constantly looking for augmented road augmentation, but also consider the cost problem at this time.The method of finding the maximum flow is to find a augmented path p for this flow from a feasible flow;The f is adjusted along p, and the new feasible flow is also tried to find the augmented path of it, and the loop is until there i

As an Internet practitioner, the most common questions asked by Layman's friends are:"How much does it cost to make a website?" "or" How much does it cost to make an app? ”。 As a complete website project and app person, today from the product manager's perspective, together to calculate what the small and medium-sized app needs to do from scratch, and in order to achieve a mission, the

How to transfer within the feasible complexity? No, look at the sky.In fact, as a graph theory workers first reaction is the cost of flow, but the number of sides too many

Topic:The table has n legs, and when the table is unbalanced, it can be cut off to achieve maximum balance. The so-called maximum balance state refers to-the longest leg of the table is more than half the number of legs of the table. But the cost of cutting the legs of the table is different, and the cost of achieving the maximum balance is minimal.Input:62 2 1 1 3 34 3 5 5 2 1Output:8The following is the l

two times to go the path is not the same and and the smallest, ask the minimum path and? Problem: From the topic we can know that the maximum flow of the problem is 2, so add a capacity of 2 source points and sinks to limit the flow, Then the weight of the edge into the cost, run once the minimum cost maximum flow.#include #include#include#includeusing namespacestd;Const intINF =999999999;Const intN =2005;
