In fact, supposedly, the algorithm should say what greedy, search, DP, two points of the basic algorithm, but I think too broad things for people who do not have the basis to speak up unclear, or write a comparison of some typical algorithm is better. And this s

About the study material, the nest to see is this articleIts definition of the data structure has been more clearly described, I am here to explain only a few small places and give their own implementation codeFirst of all, we all know Dijkstra, an algorithm used to solve the single source shortest path.Time complexity O (v^2)Then its optimization:Heap +dijTime complexity O (vlgv+e)Here are the highlights:We all thought that the dij+ heap, which was written by two forks, was vlgv+e, but what was
the key, because everyone has a mouthful want to eat into a fat mentality, So in the process of optimization, the core keywords and long tail of the key words of the scale unconsciously tilted! In fact, we have a long tail keyword optimization is a kind of wisdom, that is to circumvent the enemy's sharpness, in the local scope, the formation of the enemy's advantages, so that can be broken, successfully defeated the enemy!

Reinstalling the system is not difficult, but after installing the system do you know how many things we have to do? This can not tolerate the slightest slack, once sloppy, will likely lead to naught, even may cause data loss, information leaks!
It is an indisputable fact that Windows systems are used more slowly. Therefore, it is unavoidable to reinstall the system using Windows. Of course, reinstalling the system is not difficult, but after install

Take a look at the relaxed type:
The relaxation type is the equality of the other conditions except the non-negative constraints.
Sigma (J=1...N) AIJ *XJ
Can be turned into S=bj-sigma (J=1...N) AIJ *xj s>=0 form where S is a relaxation variable.
The basic form of relaxation type:

Sched_run: Program start, internal will be called data segmentation, map, reduce, merge and other operations
Number of map threads: indirectly controlled by the data segmentation function, the number of data blocks corresponds to Map_tasks.

Poj 3565 Ants KM
Question:
Give the coordinates of n ant and n class apple trees. To let each ant go to an apple tree, the route cannot be repeated. a feasible solution is proposed.
Analysis:
When the distance and the smallest value of a matching feasible ant are obtained, the KM algorithm can be directly used to find the matching of the minimum weight of a bipartite graph. Another approach is to assume a match first, and adjust it if there is a cross.
Code:

The slack operation is shown in the following code:Private void Relax (Directededge e) { int v=e.from (); int w=e.to (); if (distto[w]>distto[v]+e.weight ()) { distto[w]=distto[v]+e.weight (); EDGETO[W]=e; } }Vertex relaxation: For a vertex, relaxing it means rel
