reduced to AD and BC, must be intersect?It turns out that this proposition is not necessarily, but it can be found that when it can be reduced to AD and BC, AD and BC must be disjoint. Doing so will result in AD+BC > AC+BD.So as long as can reduce the side of the right and, must be able to ensure that disjoint. Then the final state becomes the edge right and the smallest state, which is the minimum match. Can be done using the KM algorithm.Appears to be a data problem and cannot be processed us
HDU_2426
This topic is a perfect match for the maximum right. we need to pay attention to two points: 1. Deal with the negative edge. 2. Note that N and M are not necessarily equal.
For the processing of the first point, I have seen two ways to deal with: ① all the sides are initialized to the negative side, so that as the N-M between all the edge is to exist to match, if the number of matches with the positive edge weight is N, there is a solution. Otherwise, no solution is available. ② The e

As mentioned above, high-precision timer is implemented through hrtimer. hrtimer uses a programmable timer to present it. It does not occupy CPU while waiting.
In the user State, when we call usleep, the thread will use hrtimer to wait for CPU usage during kernel state execution.
How to use it in kernel?

In multiple systems, the ability to log in multiple systems with an account and to have role grants (so-called single sign-on) is undoubtedly the most popular, and the Atlassian software family can integrate users of each system in a variety of ways:
1, through the unified use of external database unified user management.
2, through the LDAP server for unified user management.
3, through the Microsoft Activity Directory Unified User Management.

the top is modified to enumerate the edges to find D value, the complexity of O (N2). In fact, the complexity of the KM algorithm can be achieved O (N3). We give each y vertex a "slack" function slack, which is initialized to infinity each time we start looking for an augmented path. While looking for an augmented path, when checking for edges (i,j), if it is not in the equal sub-graph, let
Floyd-w is the shortest distance from any point to any point, because of the high complexity, so in order to only a point to any point of time to easily time out, the Dijkstra algorithm is to solve a point to any point of the distance problem, can be used for the direction of the graph or the graph, only need to pay attention to the initialization of the good, In the same way that the FLOYD-W algorithm uses the critical matrix to store the graph, we also need an array to store the origin (1) dis
the c [I]-C [J] edge. If the points on both sides are different, the points on both sides are equal, and then the sides are completed, the weight of the completed edge is regarded as 0, after completing the km operation, you can calculate the values of d [I] And d [J] based on the values of a [I] and B [J. When creating a graph, if C [I]-C [J]

the KM algorithm can be O (N3. Each y vertex is given a "relaxation amount" function slack, Which is initialized to an infinite number every time the augmented path is searched. When you check the edge (I, j) in the process of searching for the augmented path, if itNot equal subgraph, The slack [J] is changed to a smaller value of the original value and a [I] + B [J]-W [I, j.
