The MOEA Framework is a free and open source Java library for developing and experimenting with multiobjective evolutionary algorithms (MOEAs) and other general-purpose multiobjective optimization algorithms. The MOEA Framework supports genetic algorithms, differential evolution, particle swarm optimization, genetic programming, grammatical evolution, and more. A number of algorithms are provided out-of-the-box, including NSGA-II, NSGA-III, ε-MOEA, GDE3 and MOEA/D. In addition, the MOEA Framework provides the tools necessary to rapidly design, develop, execute and statistically test optimization algorithms.

BigAl is a free open source and platform independent software for calculating really BIG numbers. It supports not only standard arithmetic, but also exact period determination, predefined factorials, fibonacci with seeds, factorization, nth root, etc

The intentions of this project are as follows: 1; Determine the potential interest level in developing a basic interface for creating models in GAMS (General Algebraic Modeling System). 2; To create a sounding board for what should be added to the exist

Java-based extensible high-precision math package. Includes support for computations based on fractions. Support is included for converting to floating point numbers and BigDecimals.

This project aims to deliver a high-quality number base converter utility in Java. It will support decimal, binary, hexadecimal, octal, and a user specified base and convert between numbers of any base from 2 through 36.

Continuous wavelet transform library

Calculation of camshafts - allows to define a camshaft profile on the set trajectory which should provide the given mechanism. The trajectory can be set graphically, co-ordinates or function.

JAGAL provides implementations for directed graphs (weighted and unweighted) and varoius types of transition systems as well as utils for graph traversal and modification. JAGAL builds upon the Java library TOVAL (located at http://sourceforge.net/p/toval). To use JAGAL, make sure the TOVAL library is on the build path. This library uses and encloses jGraphX (https://github.com/jgraph/jgraphx). A documentation for JAGAL can be found under http://doku.telematik.uni-freiburg.de/jagal.

SWire is a software interface enabling us to query Stata for the executing of basic operations like reading or writing data. The core of SWire is a Java plugin which functions as a server and it can be queried by using the HTTP protocol. SWire is in essence a wrapper around the Stata-Java API and all the functions relating to this API can, therefore, be externally called by clients. SWire can be interrogated on a local network and it accepts AJAX queries, thus enabling the development of web applications which provide the user with graphical user interfaces. For example, a web application running on a browser can interact with Stata on a local network; this application could be a data entry form or an automatic report. By providing a communication protocol, SWire makes it possible to connect Stata with many other applications for data exchange and basic interaction, thereby extending the capabilities of Stata. SWire requires Stata >=13.

oj! Algorithms - ojAlgo - is Open Source Java code that has to do with mathematics, linear algebra and optimisation; particularly (but certainly not exclusively) suitable for the financial domain.

Fully playable Java game demo illustrating basic game programming technics, such as sprite animation, pixmap fonts, time or frame related game loop, affine transformations, convolution filters, sound generation and playback...

ANNJ, Another Neural Network for Java is a neural network framework for the Java programming language. It is still in an early development stage, currently supporting only feed-forward type networks, but will soon be able to handle many other types.

Interdependent Java frameworks: AMath (abstract numbers support); AFuzzy (fuzzy numbers and methods); AMathSys (flexible solvers of linear and nonlinear algebraic and differential equations); ADSM (multi-criteria ranking and grading of alternatives).

AbuGraph is a freely available Java application for the layout and visualization of directed graphs. Bound to a TCP port, it supports dynamic graph creation receiving commands from a telnet console or another third party application.

A java based neural network framework. The Auratus network is built around an XML messaging system, allowing for a complete MVC design. Additionally, Auratus networks are constructed and at the node/edge level, allowing for advanced topologies.
