The prim algorithm proves that:For AI points in the minimum cost spanning treeRemove the K-bar connected to himThe least connected graph becomes k+1 connected sub-graphChoose AI points to connect the smallest side of the outside A1 to A2Must be one side of the smallest tree.For A1 A2 two points in the minimum cost spanning treeDelete their k ' edges connected to the outside worldConnect graph becomes K ' + 1 Unicom sub-mapThey are connected to the outside world by the smallest side AI to A3Must

The third edition of the introduction to algorithms uses the insertion sort and merge order to learn about the running time of the program. I use the post-class proof to demonstrate, how to use the mathematical induction method to prove the program run time of the merge sort. On the implementation of merge sort, I have provided an almost perfect code in the previous article, the students need to learn from it. The original question is as follow

Feasibility proof of twosum problem solving algorithm in Leetcode first, introductionOn the first question in Leetcode, there have been many great man-made solutions on the Internet, and a practical algorithm has been put forward for the twosum. I consulted the answers to the blog http://www.zixue7.com/article-9576-1.html when I answered the question. To allow readers to read and understand this article more intuitively, a brief excerpt from the above

Question: If $ | z | = 1, $ proof: $ | \ frac {z-A} {1-\ overline a z} | = 1. $Proof: This question uses the analysis method: To prove $ | \ frac {z-A} {1-\ overline AZ} | = 1 $That is, $ | Z-A | ^ 2 = | 1-\ overline AZ | ^ 2. $Certificate required $ (Z-A) (\ overline Z-\ overline A) = (1-\ overline a Z) (1-A \ overline Z) $Expanded on both sides: $1-(Z \ overline A + A \ overline Z) + A \ overline A = 1-(Z

studied in an experiment (based on a method similar to Monte Carlo), there has been no formal proof of its time complexity up to now. We now claim that the complexity of zpg's solution is NP-complete. Theorem 1: determine that the solution of a Zen puzzle garden instance is NP complete.Next, let's create a proof for the next NP complete problem and give a cubic plot. Does it contain a one or two Hamilton l

Knowing Bitcoin knows that mining is very power-hungry, because Bitcoin uses a proof of workload.Workload proof refers to the work metrics that the system sets up to achieve a goal. At first, it is used in the network attack and defense, greatly improve the attacker's computational capacity, the cost of the attack went up.The workload certification needs to be done by both the worker and the verifier. It ha

' s theorem) for the situation of a Nim game (A1,a2,..., an), it is p-position when and only if a1^a2^...^an=0, where ^ represents an XOR operation. How, is not very magical. When I saw it, I thought it was magical, and it was completely unreasonable to relate to XOR or operation. But the proof of this theorem is not complex, basically is according to two kinds of position proof.5

A few days ago also to everyone said Web application firewall, including software and hardware, today, Internet Ranger to recommend a product, of course, this is the second one, is: Web page tamper-proof +web application firewall. More features, okay, nonsense do not say, the text begins: Installation is skipped, I believe that the people interested in this article can be configured according to the instructions. Here are just a few features. The pr

generated by the CA certificate and private key, you can also generate their own public and private keys, and then the public key issued by the CA. Merkel (also called Hash tree) is a binary tree consisting of a root node, a group of intermediate nodes, and a set of leaf nodes. The bottom leaf node contains the stored data or its hash value, each intermediate node is a hash of its two child node content, and the root node is also comprised of the hash value of its two child node contents. Furt

each router. Then a problem arises. A huge internet, how to believe that so many hop-on route stitching up a complete path is really the most optimized? The answer is clearly definite. The question is how to prove it.Routing algorithms in the book, the routing algorithm is basically divided into the distance vector algorithm and link state algorithm, the respective protocol masterpiece is RIP and OSPF (I am relying on these two to find the first job), it is true, but from the correctness of the
