To solve this problem, you must master the following two points: 1. minimum vertex overwrite of a bipartite graph = maximum matching of a bidirectional bipartite graph/2. 2. Using Vector in STL, you can easily create an adjacent table for graph storage. Push_back () and clear () operations are mainly used. 3. scanf () and printf () functions can easily implement the input and output in the question. For details, see the code.

The output shoshould be printed on the standard output. for each given input data set, print one integer number in a single line that gives the result (the minimum number of soldiers ). an example is given in the following table: Sample input4 0 :( 1) 1 1 :( 2) 2 3 2 :( 0) 3 :( 0) 5 3 :( 3) 1 4 2 1 :( 1) 0 2 :( 0) 0 :( 0) 4 :( 0) Sample output1 2 Sourcesoutheastern Europe 2000 Recommendjgshining is the minimum vertex overwrite of a bipa

In my recently written terrain renderingProgramIt is found that using vertex buffer cannot increase the frame rate. Using VBO can indeed increase the frame rate by at least twice, but can display lists achieve the speed of VBO? My video card is NVIDIA geforce FX 5700le, and the video card driver 81. 98. However, we found that using displaylists can save half of the video memory compared with VBO through the NVIDIA gdebugger test. I went to gamedev and

DescriptionBessie wants to navigate her spaceship through a dangerous asteroid field in the shape of an n x n grid (1 Fortunately, Bessie has a powerful weapon that can vaporize all the asteroids in any given row or column of the grid with a single shot. this weapon is quite expensive, so she wishes to use it sparingly. given the location of all the asteroids in the field, find the minimum number of shots Bessie needs to fire to eliminate all of the asteroids.

For a directed graph, given the start point and end point, ask him about the number of cut points. The cut point means that removing this point makes S and T disconnected. S and T are also cut points. First, find an arbitrary path from S to T. If there is no path, the number of cut points is N. If a path is found, mark the point in the path, first of all, it is clear that the cut point will not be on any point outside the path, because after removing the point outside, there is still the path ju

Given A point of p (x0, y0) on the plane, determine whether the point is in the Triangle ABC. The vertex coordinates of the triangle are A (xa, xb), B (xb, yb ), C (xc, yc ). You can use the area method to determine the area. The method S (A, B, C) indicates the area of the Triangle ABC.1. If abs (S (A, B, C) = abs (S (P, B, C) + abs (S (A, P, C )) + abs (S (A, B, P), P is inside or beside the Triangle ABC; if there is abs (S (P, B, C )) abs (S (A, P,

Import Determines whether the touch point is inside a polygon.Method 1. Mathematical Methods The advantage of this method is that any platform can be used, not only for AndroidAlgorithm: Solve the intersection of the horizontal line and each side of the polygon through this point. If the intersection of one side is odd, it is true. Okay, we actually need to look at the intersection of the single side ray of this point and the polygon.

The minimum point coverage problem of general graphs is a NPC problem, and there is no better polynomial algorithm for ha. But this problem has a little special place, each side must contain the first 30 points of one, so this question can enumerate the money 30 points of the selected and not selected state, the subsequent point corresponding to the state is unique. So this is the dfs+ feasibility of the reduction of the branch and the optimal reduction of the answer.#include SCU OJ 4439:

IOS sometimes needs to determine whether to touch a certain image area. A small example is provided here to create an area using cgpath. The area is the area where the line segments between two points in the path are closed and merged. For example, a simple rectangle is created here. Then, you can use the cgpath function to determine whether the vertex is in the region. -(Void) viewdidload {[Super viewdidload]; cgmutablepathref pathref = callback (

In C ++, the arrow operator (->) vs the vertex operator (.) A pointer is displayed on the left.An object is on the left.If P is a pointer, p-> function ();If P is an object, P. function ();Remember-> the left must be a pointer, and the left must be an object or a struct, generally a class object.First, we will introduce the structure in C ++. For a structure, Struct mystruct{Int member_a;}; If there is a variable mystruct S, you can use S. member_
