Transferred from: http://www.cnblogs.com/codingmylife/archive/2012/10/21/2732980.htmlThese days written several times, a continuous encounter with a common ranking algorithm stability of the problem, often or more choice, for me and the same as I am unsure of the classmate is not a can easily jump to the conclusion of the topic, of course, if you have written before the writing has been remembered in the data structure of the book which is stable, whi
Many friends are engaged in Enterprise website optimization work, however, in this process we from the site did not rank to gradually get a good ranking, the process we have to pay unremitting efforts, But how to get the rankings after the weight of the site and ranked better stability in an ideal position is our every optimization personnel are worth thinking about the problem, we have to gossip short continue to enter today's theme, the impact of th
Selecting sorting, fast sorting, Hill sorting, and heap sorting are not stable sorting algorithms, while Bubble sorting, insert sorting, Merge Sorting, and base sorting are stable sorting algorithms.
First, we should all know the stability of sorting algorithms, in general, it can ensure that the first two equal numbers are sorted in the same order before and after the sequence. In a simple form, if AI = AJ, the AI is in the front of the location, and
I have introduced the basic knowledge and security of wireless networks in the previous articles. This article describes the security of wireless networks. This article analyzes the location of wireless devices and the interference of wireless signals, and hopes to help you.
I. Stability of wireless networks: What is stability? That is to say, the signal should continue to be good, and the signal strength s
1. SortingSorting is an important operation in computer programming, so it is an important task to study and study various sorting algorithms.2. Type of sortingDepending on the number of sorted records and the memory in the sorting process, sorting can be divided into internal and external sorting.Internal sorting: Refers to the process of storing a sorted record in the computer's memory for sorting.External sort: Refers to the number of records with sorting so large that the memory does not hol
The article about the stability of wireless network introduced on the network, can be said to be countless, through these articles, we can also understand the related configuration process. So for the security of wireless network stability. Let's have a deep analysis. For the use of wireless networks, we must be familiar with, but we are in the process of using the network is often unstable state, then what
1. Select sort, quick sort, hill sort, heap sort not a stable sorting algorithm,
Bubble sort, insert sort, merge sort, and Cardinal sort are stable sorting algorithms.
2. What is the significance of studying the stability of sequencing algorithms?
First of all, the stability of the sorting algorithm should be known, popularly speaking is to ensure that the first two of the same sort of data in the seque

The 1 Stability test tests the system's long-term stability and performance. During the system operation, the system pressure, observing the various performance indicators of the system, as well as the server indicators.
2 Test scenario: Simulate normal pressure, simulate the actual number of users in the daily operation. Data must be sto
For the site rankings can not stabilize the situation, many webmasters have encountered. And this is also let stationmaster very distressed things, because their own very easy to optimize the site rankings, probably because of the search algorithm to change the reason, so that their own web site has not been sitting on the position of the current ranking has declined. For this situation, I think the main reason is still appearing in the site, after all, search the algorithm and how to change is
Many of us are using wireless networks. But how can we solve the problem? We need to have a root problem spirit to solve the problems we encounter.
I. Stability of wireless networks:
What is stability? That is to say, the signal should continue to be good, and the signal strength should remain unchanged. Even if the signal is weak, the signal cannot be weak for a while, but not for a while. The
We must be familiar with the use of wireless networks, but we often encounter unstable network conditions during use. Why?

What is stability? That is to say, the signal should continue to be good, and the signal strength should remain unchanged. Even if the signal is weak, the signal cannot be weak for a while, but not for a while. The
on the promotion of the Site keyword ranking method, the network has appeared many many, today talk about basic, but also the most easily overlooked by webmaster Friends of the six "stability" factors. These factors seem obscure, but it is you in the site to do SEO when the biggest stumbling block.
First, the website server stability
The reason for the stability
The read stability in DB2 is the knowledge that every DBA must master. It ensures that "non-repeated reading" is not possible and deserves further study.
Read stability RS) only lock the rows retrieved by the application in the work unit. It ensures that any qualified row reads during the execution of a work unit are not modified by other application processes before a work unit is completed, make sure tha
Conclusion: Selection of sorting, fast sorting, Hill sorting, and heap sorting are not stable sorting algorithms, while Bubble sorting, insert sorting, Merge Sorting, and base sorting are stable sorting algorithms.
Stability of the Sorting Algorithm: if multiple records with the same keywords exist in the sequence to be sorted, and the relative sequence of these records remains unchanged, the algorithm is stable; if the order of records is changed aft
On a "web site to establish a cycle of eco-system guidance ranking stability into the home page (ii)" The article mainly learned the basic code and the promotion of the chain outside the site, through the two major role of learning can help the site to establish a qualified search engine crawl routes, help the site cycle more favorable, But a website relies on these cycle content is not a long-term solution, we also need to use more methods and techni
select a value that is just a median value, the array can be classified.First layer recursion, loop N times, second layer loop 2*(N/2 )......So there are n + 2 (n/2) + 4 (n/4) +... + N * (n/n) = N +... + n = K * n = log2 (n) * nTherefore, the algorithm complexity is O (log2 (n) * n)In other cases, it will only be worse than this case. The worst case is that the middle selected each time is the minimum or maximum value, so it will become the exchange method (because recursion is used, the situat
First of all, the stability of the sorting algorithm should be known, popularly speaking is to ensure that the first 2 equal number of the sequence before and after the order and the ordering of their two before and after the position of the same order. In a simple formalization, if AI = Aj,ai was originally in position, the AI still had to be in the AJ position before the order.Second, describe the benefits of st
Site in the construction and maintenance, will encounter a lot of problems, which is very important is the stability. So here in gold wisdom on personal experience and views of this to share with you:
First: To ensure that the site positioning must be clear.
This is directly related to the stability of the site source program. Because the website does different content and the development direction diffe
can be divided equally.First-level recursion, cyclic n-times, second-layer cyclic 2* (N/2) ...So altogether n+2 (N/2) +4 (N/4) +...+n* (n/n) = N+N+N+...+N=K*N=LOG2 (n) *nSo the algorithmic complexity is O (log2 (n) *n)Other situations are only worse than this, and the worst case scenario is that each middle is a minimum or maximum value, and then he becomes a swap (which is worse because recursion is used). But how likely do you think this is going to happen? Oh, you don't have to worry about i
With the rapid development of wireless technology, the home wireless network has been developed from 802.11b 11Mbps to 802.11g 54Mbps, and a lot of personal users with special requirements for wireless coverage and transmission speed have adopted more advanced extension 54M and 108Mbps network.
Although the technology can achieve high-speed wireless transmission, including Internet extranet and the network of computers between the data transmission, but the wireless signal and transmission spee
