If these operations are performed on a one-dimensional sequence, then the line segment tree can be used. But now the question expands these operations to two-dimensional, recalling that the essence of the Line Segment tree is a binary line segment, then for a two-dimensional matrix, expansion should be a quartile matrix.

become the initial point of the second time slice, then on the second time slice on the C point and the new target point to construct a triangle to calculate the new VT, and then into the third time slice, so repeated.Assuming the coordinates of the initial state of the missile and the target are (x1,y1), (x, y), constructs the right triangle Abe, which is used to seek the sine and cosine of the ∠a, because the VT is set by itself, we need to calcula
Note: This tutorial is I try to use scikit-learn some experience, Scikit-learn really super easy to get started, simple and practical. 30 minutes learning to call the basic regression method and the integration method should be enough.This article mainly refers to the official website of Scikit-learn.Preface: This tutorial mainly uses the most basic function of numpy, used to generate data, matplotlib used for drawing, Scikit-learn is used to call machine learning method.

In the previous section, we talked about how to find the path. During discussions with friends, we were not very right. We went a long way. In fact, the code is mainly about determining the direction, for example, the target is on the top right, it should be right first or first, but it will not be processed. If this is done, the effect will be better, but it will inevitably lead to detours. Greedy is like this, not optimal, close to optimal. I also hope that other students will have some commen
The study of iterative methodIterative method is a common algorithm design method for solving the approximate root of equations or equations. Set the equation to f (x) = 0, use a mathematical method to derive the equivalent form x=g (x), and then follow these steps:(1) Select an approximate root of the equation and assign it to the variable x0;(2) The value of x0 is stored in the variable x1, then g (x1) is
In C + +, the temporary object calls the destructor as soon as it is not needed, releasing the resource it occupies, while the named object invokes the destructor in turn, in reverse order of creation.

interpolation algorithm is to find its adjacent integer value (int (x0 ' +0.5f), int (y0 ' +0.5f)) (not rounded in the previous article). We now look for the four points next to the location of x0 ', Y0 ', based on the relationship between these four points and (x0 ', y0 ') distance to calculate the pixel values in the target image (x, y). The algorithm is described as follows:
(1) Calculate the ratio between the source image and the target image width and height

0-1 integer Programming and implicit enumeration-feeling the charm of pruningInteger Planning is a special case of linear programming, that is, when the constraint is a variable integer, the linear programming becomes the integer plan. If all variables are required to be integers, it is a pure integer plan ; If some of the variables are allowed to be integers, it is called mixed integer planning . the 0-1 integer plan to be discussed in this paper is a special case of pure integer programming, t
