Jafaran (Java Fast Random) provides fast, and for some more random, implementations of java.util.Random, with additional nextXXX() methods, and methods to retrieve and restore state. The names of implementations contain "Conc" (for concurrent) if they are thread-safe and non-blocking, or "Seq" (for sequential) if they are not thread-safe. Also provides an implementation of Ziggurat algorithm (based on J. A. Doornik paper, 2005), used by nextGaussian() methods of the provided implementations. Requires Java 5 or later. Also available on github since 2015/12/13: https://github.com/jeffhain/jafaran Principal classes: - Implementations using Mersenne-Twister algorithm (good pseudo-randomness): MTSyncRNG MTSeqRNG - Implementations using Marsaglia Xor-Shift (fast): MXSIntSeqRNG (32 bits) MXSLongSeqRNG (64 bits) (nextLong() faster, larger period) - Ziggurat: Random-based implementation of Ziggurat algorithm.

Some utility function and/or class to convert date from Gregorian calendar to Jalali (Hejri Shamsi) calendar in PHP, Delphi (and some other in future) with very fast algorithm.

Fastest string utility is java library (JAR ) for string operation . This library is very easy to use, very fast and very efficient in string operations such as split, toUpperCase, toLowerCase, replace, delete, regular expression and others.

JGAL is a Java Genetic Algorithms Library.

Java KellyCriterion Calculator

A 100% Pure Java(tm) Polygon Triangulation Library

A Java package for pretty-printing a text by deciding where to introduce line-breaks and indentation. A Java implementation of Derek Oppen\'s pretty printing algorithm. It is _not_ a pretty printer for Java code, though it could be used to write one.

Very lightweight and easy to use library that allows you to generate truly random numbers by means of Random.Org service. Library offers optimized algorithms for obtaining single random number or more random numbers at once, sequences of numbers, random strings etc. Also allows you to check quota. It provides algorithm to generate unspecified number of random numbers of certain total value. This algorithm still keeps server load low by sending as large requests as possible, yet all integers are truly random. ******************************************* Current version 1.5 is considered as STABLE version. All methods and whole class are documented via Javadoc. Credit goes to http://www.random.org

This project is java version of the SQL functions as defined by the Transact-SQL programming language for the MS SQL 2000. It is pure 100% Java implementation for the famous SQL Functions such as CONVERT, PATINDEX or DATEDIFF.

This program benchmarks the following sorting algorithms implemented in Java: Quick Sort, Heap Sort, Merge Sort, Selection Sort, and Bubble Sort. A command line GUI was created to facilitate all your benchmark needs.

A simple statemachine library in java. It uses the memento pattern so the state is stored outside the machine so it is easier to cluster a solution using this statemachine.

Java implementation of the most commonly used algorithms for exact string matching, where the pattern is given first.
