Respecting the fruits of labor and transferring from http://www.cnblogs.com/biyeymyhjob/archive/2012/07/30/2615542.htmlPrim algorithm1. OverviewPrimm algorithm (prim algorithm), an algorithm in graph theory, can search for the smallest spanning tree in weighted connected graphs. This means that the subset of edges searched by this

Logistic regression algorithm debugging First, the principle of the algorithmLogistic regression algorithm is an optimization algorithm, which is mainly used for classification problems with only two kinds of labels. The principle is to use a straight line to fit some data points and divide the data set. Broadly speaking, this is also a multivariate linear regres

Operating System Series Learning to this point, found a lot of learned but long useless knowledge, over time, slowly forgotten. When the day is needed, but found to have forgotten almost, even if the document (Word, etc.), still have to learn from the beginning. Study the first semester, found that a lot of things can be learned from the blog, there are a lot of bloggers have worked hard to organize a lot of useful Bowen. So, I take this opportunity, also slowly began to organize some blog posts

About Lis (least increasing subsequence, which can be translated into the longest ascending subsequence and the longest ascending subsequence), its O (n2) and O (NLGN)AlgorithmFor more information, see [1] [2]. The O (n2) algorithm was heard a long time ago that it is not fresh, but O (NLGN) the algorithm is the first time I have heard of it. I think it is very fresh and awesome. Since many people refer t

Data structures and algorithms in JavaScript (V): Classic KMP algorithm, data structure and algorithm kmp KMP algorithm and BM algorithm KMP is a classic algorithm for prefix matching and BM suffix matching. It can be seen that the difference between prefix matching and suff

Dijkstra algorithm1. Definition OverviewThe Dijkstra (Dijkstra) algorithm is a typical single-source shortest path algorithm that calculates the shortest path of a node to all other nodes. The main feature is to extend from the center of the starting point to the outer layer until it expands to the end point. Dijkstra algorithm is a very representative shortest p

KMP Algorithm and BM algorithm KMP is the classical algorithm of prefix matching and bm suffix matching, it can be seen that the difference between prefix matching and suffix matching is only the different order of comparison. Prefix matching is: the comparison of pattern strings and parent strings from left to right, the movement of pattern strings is also fro

The HITS (Hyperlink-Induced Topic Search) algorithm was first proposed by Dr. Jon kleberger of Cornell University in 1997, part of the "CLEVER" Research project for IBM's Almaden Research Center. The HITS algorithm is a very basic and important algorithm in link analysis. Currently, it has been used as a link analysis algorit
