Base sorting introduction and Java implementation, base sorting introduction java Basic Ideas Base sorting (RadixSort) is developed on the basis of Bucket sorting, both of which are advanced implementations of distributed sorting. The basic idea of DistributiveSort: the sorting process does not need to compare keywords, but is sorted by the "Allocation" and "Collection" processes. Their time complexity can reach the linear order: O (n ). Base sorting is a stable sorting algorithm, but it has som

IntroductionIn the previous section, we introduced the general idea of Multi-probe LSH algorithm, in order not to appear too jumbled blog article, so the topic is divided into several articles to write.In this section of the article, I will give you a detailed description of the method of generating the perturbation vector sequence (a sequence of perturbation vectors) and related analysis.Step-up detection (step-wise probing)N-step perturbation vector δ has n non-0 coordinates, depending on the

quite simple, and I'll take a look at the cardinal sort flow ....We have 9 buckets, and the numbers in the array are allocated in the buckets as values:PS: Image from the network, invasion and deletionAbove we found: if the bucket is recycled sequentially , then our sort is done ~However, in general, our array elements are not only single digit number, then the number of high-level number how to do it?? Fo

To illustrate the process of sorting buckets, suppose there are now a={0.78,0.17,0.39,0.26,0.72,0.94,0.21,0.12,0.23,0.68}, the buckets are sorted as follows:Study on the count sort we know ———— count sort is assumed that the input is made up of integers in a small range, whereas bucket ordering assumes that the input is produced by a random process that distributes the elements evenly and independently acro

maximum and minimum values of the array to be sorted plus 1), this makes the count sort for arrays with a large data range, which requires a lot of time and memory (if the data is scattered, there are actually a large number of 0 in Occupy a lot of space).Best case: T (n) = O (n+k)Worst case: T (n) = O (n+k)Average condition: T (n) = O (n+k)Two, bucket sort (bucket sort)Bucket sorting is an upgraded version of the Count sort. It takes advantage of the mapping of functions, the key to efficiency

and the hash table. The contents of the hash table are recommended to look at this blog hash table . In terms of hashing , it is simply a kind of compression of any length of message to a fixed length, such as a school student number range from 00000~99999, a total of 5 digits, if each number corresponds to an index, then is 100,000 index, But if we use the latter 3-bit as the index, then the scope of the index becomes 000~999, of course, the case of conflict, this is the hash conflict (hash co

independently across the interval [0,1]. When the input of the bucket sort conforms to the uniform distribution, it can be expected to run linearly. The idea of barrel sequencing is: Divide the interval [0,1] into n equal-sized sub-ranges, become buckets (buckets), then distribute n input numbers into buckets, sort the number of

Last, we analyzed the implementation of the chain address method of hash table, that is, the data structure of "Array + linked list" is used. This time, the introduction of a hash bucket To solve the conflict, that is, hash function hash () to the key to the hash value, and then according to the capacity of the bucket (the capacity of the bucket fixed), and "In addition to" to locate a hash subscript, Creates a hash bucket (Bucket) for the hash value. Complete implementation code: link. Below, a

number of buckets in the hash table, and n is the number of keywords. The larger the loading factor, the more serious the hash conflict is. For the first, the general situation does not need their own consideration, to find someone else to design, but also very suitable for their own hash function with the line. Therefore, the design problem of hash function is not considered (the current understanding is that) For the second article, the book wrote

architecture-first look at Couchbase How the architect organizes, then describes the naming convention in Couchbase, and then delves into how the stored data is queried, and finally discusses replication across data centers.ArchitectureCouchbase is a true shared-nothing architecture, which means there is no single point of failure because each node in the cluster is self-sufficient and independent. What is the way distributed technology works? --Each node does not share any memory or hard disk

these two values) constitute most of the data in the table (data skew), related queries may not help reduce the need to meet the query i/ o Quantity (e.g. query Status=1). Creating a histogram allows the cost-based optimizer to know when to use the index most appropriately, or when to return 80% of the records in a table based on the value in the WHERE clause.Three. Histogram classification and principle Equal-frequency histogram: For datasets that contain very few different values, th

Before introducing hash index, it is important to introduce the hash function so that we can unders
