I node is (I-1)/2. Its subnode subscript is 2 * I + 1 and 2 * I + 2 respectively. For example, the subnode subscripts of the first 0th nodes are 1 and 2 respectively. Heap operation-insert and delete The following describes how to create, insert, and delete the smallest heap in "Data Structure C ++ language description Description", and then shows the implementation code. It is best to first clarify the diagram and then look at the code. Heap insertion Each insert operation puts the new data at

The classical literature of feature detection and tracking is the article of Shi and Tomasi 1994 (see Reference), although it is very classical. In this paper, a feature extraction method, a tracking algorithm based on image affine transformation model (translation component without deformation component) and a tracking method, which can be used to detect the good feature, are presented. which are bad featu

, from east to West for the positive direction, the unit length of 1 meters, so that we get a first-to-last line. The starting point of setting Frog A is x, and Frog B's starting point coordinates are Y. Frog A can jump M m at a time, Frog B can jump n meters at a time, and two frogs will spend the same time jumping once. Latitude line total length l m. Now you have to find out how many times they have jumped before they meet.InputThe input includes only one line of 5 integer x,y,m,n,l, where X≠

Classical algorithm Learning--Quick sorting Quick sorting should be considered the most commonly used algorithm in the interview test, and the interviewers are very fond of it. The efficiency of sorting is more efficient in the same O (N*logn), so it is often adopted, and the thought of it is also used in the thought of division and recursion. Sample code upload to: Https://github.com/chenyufeng1991/QuickSort The basic idea of the algorithm is: (1) F

nearest neighbor in the feature space) Most of the samples belong to a category, then the sample belongs to that category.IX, Naive BayesIn many classification models, the two most widely used classification models are decision tree (decision tree model) and naive Bayesian model (Naive Bayesian MODEL,NBC). Naive Bayesian model originates from classical mathematics theory, has a solid mathematical foundation, and stable classification efficiency. At t

I would like to give you a detailed analysis of photoshop software and share with you the tutorial on making classical freehand circular photos.Tutorial sharing:Import the image to be created and use the oval box selection tool to select the appropriate position. As shown in the following figure:Create a new canvas with a length of 10 cm, 120 pixels, and a white color. Drag (crop) the part selected in the first step to create a new canvas and adjust t

accuracy. The new data set of the modified weights is sent to the lower classifier for training, and finally the results of each training are fused together as the final decision classifier.8, KNNK Nearest Neighbor Classification algorithm is a theoretically mature method and one of the simplest machine learning algorithms. The idea of this algorithm is that if a sample is in the K most similar (i.e. nearest neighbor) sample in the feature space, most of them belong to a category, then the samp

recursive work stack.) In particular, each call to the function itself to save the contents include: local variables, formal parameters, call function address, return value. Then, if you call n times recursively, allocate n local variables, n parameters, n call function addresses, n return values. This is bound to affect efficiency. ） V. Classical realization Classic question: The Eight Queens question?? The eight Queens question, is an

Elegant classical color ratio is good to grasp, color matching can directly reduce the primary color saturation to get a preliminary neutral picture, and then to highlight and dark to add a little light to increase the classical flavor, later rendering some smoke, the overall soft treatment to make aesthetic effect can be. Original Final effect 1, open the material picture, cr

Pull up the ancient costume character picture Tanqing classical color The accuracy of the material picture shooting is not very high, the background and the character part have more miscellaneous points. It is necessary to deal with the character and background noise before processing. The main color is best to choose the more classical color, this can better foil the characters of the ancient costume, hig

The method used is a bit like imitation hand-painted, but the effect is closer to hand-painted. People face, facial features, hair, clothes and so on need to repaint, the process is more complex. Before drawing the best to find some classical hand-drawn characters, reference to the use of color and charm description. 　　Photoshop Tutorial artwork Final effect 1, open the material picture, press CTRL + J to copy a layer of bac

Material picture background and characters are classical style, but the weather reasons, the characters and background is not too fusion. When dealing with the sky part of the first to increase the light effect, and then the main color into the classical yellow-blue, and finally increase the dark angle, beautify the details can be. Original Final effect 1, open the material

implications of convolution. The most classical explanation: the dimension-reducing strike Convolution is the two-function U (x,y) = f (x) g (Y) roll into a function V (t), commonly known as the reduction of the dimension of the attack.Image.png 1) How to roll. Given that the function f and G should be equal, or that the variables x and y should be equal, one option would be to roll up the line x+y = t: 2. What is the use of volume? Can be used to mu

Algorithm VI: DFS (depth first search) Depth-First search algorithm (Depth-first-search) is one of the search algorithms. It traverses the tree's nodes along the depth of the tree, searching the branches of the tree as deep as possible. When all the edges of node v have been explor

It was presented by Marco Dorigo in his doctoral dissertation in 1992, inspired by the behavior of ants discovering pathways in the search for food. Ant colony algorithm is a kind of simulated evolutionary algorithm, the preliminary research show

model) and naive Bayesian model (Naive Bayesian MODEL,NBC). naive Bayesian model originates from classical mathematics theory, has a solid mathematical foundation, and stable classification efficiency. At the same time, the NBC model has few parameters to estimate, less sensitive to missing data, and simpler algorithm. In theory, the NBC model has the smallest error rate compared to other classification methods. But this is not always the case, beca

add K to S (the selected distance is the shortest path length of V to K).C. Change the distance of each vertex in the U with K as the new consideration; If the distance from the source point v to the vertex u (through vertex K) is shorter than the original distance (without the vertex K), the distance value of the vertex U is modified, the distance of the vertex k of the modified distance value and the right of the edge are added.D. Repeat steps b and c until all vertices are contained in S.Ins
