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.

A Thread and Task Manager. Execute Tasks in a Thread Pool.

Sorting algorithm performance testing using a generic test interface

JavaFrameApplet is a generic base in Java for Applet in JFrame games!

JavaGO is an Open Source Java library for the Game of GO (weiqi, baduk) analysis. Implements: base game classes, montecarlo simulations, SGF reader/writer, game variants, GTP, etc. Elegant interfaces/class design. Speed efficient w/small footprint. TDD.

A set of helper and utility classes, APIs and tools for the Java Programming Language. For more details - pleas visit the project homepage.

A graph library, developed in Java.

JavaStates is a Java library designed to statically describe and animate the states of Java objects, while ensuring that the integrity of states is retained at all times. JavaStates brings OO Programming style to interface spec, design and coding.

An optimized java library for genetic algorithms. The library is designed to be fast and memory light, but still very easy to use.

The source code has been migrated and is now hosted on Github: https://github.com/jenetics/jenetics Jenetics is an advanced Genetic Algorithm, Evolutionary Algorithm and Genetic Programming library, respectively, written in modern day Java. It is designed with a clear separation of the several algorithm concepts, e. g. Gene, Chromosome, Genotype, Phenotype, Population and fitness Function. Jenetics allows you to minimize or maximize the given fitness function without tweaking it. In contrast to other GA implementations, the library uses the concept of an evolution stream (EvolutionStream) for executing the evolution steps. Since the EvolutionStream implements the Java Stream interface, it works smoothly with the rest of the Java Stream API.

http://jocdelavida.piposerver.com - Online implementation of Conway's Game of the Life 0 players game, but using entities based on the nature, like animals or plants who born, grow up, reproduces breed and die. Written in Java 6 and Adobe Flex 3.

An online judge system to judge the ACM-ICPC programming contests.

An implementation of "k-Way Merging" as described in "Fundamentals of Data Structures" by Horowitz/Sahni. NOTE: This project has been moved to http://code.google.com/p/kway/

K-automaton is a new parsing (syntactic analysis) machine isomorphous to language. Implemented in Java. Can generate Java code from grammars described in EBNF.

An enhanced Simulator based on Agent Grid Repast.It has some bugs cleared from Agent Grid Repast and has enhanced features on Group Selection Policy.

The project contains algorithms for locating the most central groups in complex networks. In particular implementations of various centrality measures and heuristic search algorithms. All functionality is exposed via XML-RPC for easier exploitation.
