between any two points is updated to:by knowing that, when compared to only allowing transit through the number 1th vertices, this allows the transfer through vertices 1 and 2nd, making e[1][3] and e[4][3] shorter distances. in the same vein, the shortest distance between any two points is continued in cases where only 1, 2, and 3rd vertices are allowed to be brokered. The shortest distance between any two points is updated as follows:Finally, all vertices are allowed as a transit, and the fina

Today began to study the Redis source code some of the tools in the implementation of the tool class in any language, the implementation of the algorithm principle should be the same, so you can take this opportunity to learn some of the more classical algorithms. Like I see today. CRC cyclic redundancy check algorithm and rand random number generation algorithm.

Php user password encryption algorithm analysis [Discuz encryption algorithm], discuz Encryption Algorithm This example describes the php user password encryption algorithm. We will share this with you for your reference. The details are as follows: During secondary development with Discuz today, the user name and pass

Coincidentally, almost all of the popular hash map uses the DJB hash function, commonly known as "TIMES33" algorithm. Perl, Berkeley DB, Apache, MFC, STL, and so on. Times33 's algorithm is also very simple, is constantly multiply by 33. Nhash = nhash*33 + *key++; I didn't find any theory to illustrate the rationality of this algorithm, it is said that only

The minimum spanning tree can have multiple in a graph, but if the weights of the edges in a graph are different, then the smallest spanning tree may only exist, and it is easy to prove it with contradiction.Of course the minimum spanning tree is also a graph that contains the weights and the lowest sub-graphs of all nodes.In a graph of the least weight of the edge must be in the smallest spanning tree, if a graph contains a ring, the ring of the largest weight of the edge must not be in the sma

1. Brief Introduction I am going to review several typical Tree structures recently. This article mainly focuses on Binary Search trees. The English name is Binary Search Tree (BST ).This article mainly summarizes the search algorithm, insertion algorithm, and deletion algorithm of the Binary Search Tree. 2. Search Algorithms This is relatively simple, either fou

First, the dictionary order method1) from the right end of the sequence p, scan to the left until you find the first number that is smaller than the number on the right.2) from the right, find all the smallest numbers in the larger number, ie.3) Exchange with.4) Flip the sequence on the right to get the next permutation of the dictionary order.5) Repeat the above steps until you get the largest order in the dictionary order, that is, the left number is larger than the right.Dictionary order Meth

The dijkstra--of the halfway algorithm is understood from the angle of routing algorithm A previous Wireless sensor network course (WSN) assigned a Dijkstra algorithm to any language in any environment. I thought, good ah, had been shouting no time to worry about the algorithm, this can be used as a breakthrough point

There are also contacts for the program paging algorithm. In general, there are two kinds of paging algorithms, one is the traditional ADO paging, the other is the select top paging algorithm. For small data tables, such as ten thousand or twenty thousand of the amount of data table, I tend to use the ADO algorithm, for large data tables, you must adopt the latte

On the extended Euclidean algorithm (Extended Euclidean algorithm), I was working on the classic topic of frog dating to get access to this algorithm. There is also an AC code and a solution to the problem.Content: Known A, B, solves a set of X, Y, and satisfies the Bézout equation: Ax+by =gcd (A, B)Extending Euclid's algorit
