Topic: Given an S1 graph, the longest public shortest path to T1 and S2 to T2 is obtained.to S1 T1 S2 T2 as the source to do 4 times the shortestIf there is a forward edge that satisfies the distance from the s to the starting point + the distance from the edge length + the end point to the T =s the shortest path to T, then this edge can be on the quickest way from S to TWe carry all the S1 to the shortest path from the T1 to the S2 to the T2.It's easy to prove that the graph must have no ring.

Sorting It all Out poj-1094The main topic: give some of the size of the relationship between the string, ask whether to get a unique string sequence, the value of the meeting weight with the subscript increment.Note: Up to 26 letters, all uppercase.Idea: Obviously, it's easy to think of processing with toposort, for each size relationship we just read, we do a topological sort, because the number of points is up to 26, so the total time complexity is $10^2$. Then through the surface, you can fin

Why use the leaf-spine topology network? (1) The structure of the three-layer network has developed very mature, but the leaf-spine (leaf node, spine ridge node) structure is becoming more and more popular. How should network designers choose? Despite the wide application and mature technology of the layer-3 network architecture, with the development of technology, its bottlenecks also emerge, resulting in more and more network engineers to abandon t

from: http://blog.csdn.net/derekjiang/article/details/9040243Conceptual UnderstandingIn the original, a graph was used to illustrate the concurrency mechanism of the topology runtime in a storm cluster.In fact, when a topology is running in storm cluster, its concurrency is mostly about 3 logical entities:worker,executor and Task1. The worker is the process that runs on the work node and is created by the S

The network topology refers to the physical layout of devices connected by transmission media. There are multiple ways to connect the various devices involved in LAN work with media. In fact, there are only several ways to fit LAN work. If a network only connects several devices, the easiest way is to directly connect them together. This connection is called a point-to-point connection. The network formed in this way is called a fully interconnected n
