From the perspective of finite state machine to understand Knuth-morris-pratt algorithm (also known as KMP algorithm, "See the Pornography" algorithm)

://github.com/aliencool/Algorithm/tree/master/Searching Conclusion: Why are many people called KMP algorithm called "Look at the pornography" algorithm, because it is pinyin? Too low to explain this, why? Because, KMP he does not backtrack, every time, isPattern strings themselves (you know), so it's called "Look at the pornography" algorithm.

The KMP (Knuth–morris–pratt) algorithm that I understand

Suppose you want to match needle in haystack .To understand KMP first need to understand the two concepts proper prefix and proper suffix, due to find no suitable translation, temporarily called the real prefix and the true suffix. true prefix (Proper prefix): A prefix string that contains at least one trailing character in a string. For example, all true prefixes of "Snape" are "S", "Sn", "Sna", and "snap". true suffix (Proper suffix): A string that contains at least one suf

Random shuffling algorithm Knuth shuffle and wrong-row formula

Knuth random Shuffle algorithm: for example, there are now 54 cards, how to shuffle to ensure randomness. You can think of this, from the very end of a card to wash, for each card, numbered in the cards in front of any one of the cards selected and the current card to exchange, until the first card to wash. The reference code is as follows:void Knuth () {

Go to book review: To talk about the algorithm book of GIS

The http://blog.3snews.net/space.php?uid=16796do=blogid=22870 of Jiang waves1984 Turing Award winner, the inventor of the Pascal language, Professor Niklaus Wirth, has given the program a classic definition of "program = algorithm + data structure", sharply. In my opinion, the algorithm and the data structure are like the methodology and epistemology in philosophy, the former clarifies the idea of solving a

Linear can be divided intoFor a data set:If there is a hyper-planar x that can precisely divide the positive and negative samples in D into the sides of S, the hyper-plane is as follows:Then the data set D is linearly divided, otherwise, it is not possible to be divided.W is called the normal vector, which determines the direction of the super plane, and B is the displacement amount, which determines the distance between the super plane and the origin point.The distance from any point in the

Data structure and Algorithm analysis: C Language Description _ Original book second Edition CH3 tables, stacks and queues _reading notes

main purpose is to separate the specific implementations of the abstract data types from their functions. The program must know what the operation is doing, but it's better if you don't know how to do it.tables, stacks, and queues may be three basic data structures in all computer science, and a large number of examples attest to their wide range of uses. In particular. We see how the stack is used to record procedures and function calls, and how recursion is actually implemented. It is importa
