FrEAK, the Free Evolutionary Algorithm Kit, is a toolkit to design and analyze evolutionary algorithms, written in Java.

A math application written in Java. Its features include 2D and 3D graph plotting, scripting, user-defined variables and functions and skinnable GUI. This project is not maintained at the moment.

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

GeoGebra is free and multi-platform dynamic mathematics software for learning and teaching geometry, algebra, statistics, and calculus. Download the free software at http://www.geogebra.org. Find the source code at http://www.geogebra.org/trac

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.

JCalc is GUI calculator written entirely in Java. It can be run cross-platform on any OS with a Java Virtual Machine. It shall be portable, stable, and efficient.

A web-based, automated search engine that responds to user feedback through the use of artificial intelligence.

Logiciel de modélisation, simulation et traitement du signal adapté aux applications lidar.

MATHLIB3D: MATHLIB3D is a Vector/Matrix/Quaternion/Plane/Polynomial C++/Java library targeting either precision or fast mathematical operations executed on vectors, matrices and quaternions.

MatrixOps is a console program written in Java that makes matrix operations. The goal of this project is to work as a Java tutorial, using some functions/programs typically made at school, with full documentation of the API.

NumberMonkey is a calculator written in Java, including basic operations and additional functions; new functions are added with each release. It can be implemented as a standalone desktop application or as an applet within a webpage.

superseded by SgpDec http://sgpdec.sf.net Java implementation of the holonomy algorithm for the algebraic hierarchical decomposition of finite state automata.

Paean is a tool to demonstrate in real-time the effect of various error-correcting codes on data transmitted via several channel models.

SEPIA provides implementations for various types of Petri nets. Along Place/Transition-nets, it supports Petri nets with distinguishable token colors and defines coloured workflow nets, where coloured tokens are interpreted as data elements used during process execution. To support information flow analysis of processes, SEPIA defines so-called IF-Nets, tailored for security-oriented workflow modeling which enable users to assign security-levels (HIGH, LOW) to transitions, data elements and persons/agents participating in the process execution. SEPIA builds upon TOVAL (http://sourceforge.net/p/toval), JAGAL (http://sourceforge.net/p/jagal) and SEWOL (https://sourceforge.net/projects/jawl/). To use SEPIA, make sure these libraries are on the build path. SEPIA encloses the Multi Schema Validator (https://msv.java.net/) and isorelax (http://iso-relax.sourceforge.net/) The documentation can be found under http://doku.telematik.uni-freiburg.de/sepia.

A statistics graphing tool that allows for users to input data and have it represented graphically.

Java library of statistical distribution functions. Classes implement the PDF, CDF, and (usually) quantile and random variate generation for many common distributions.

This project has moved to http://code.google.com/p/synthetic/

Misc packages including a matrix application, a text based minesweeper, and simple console functions bundled to be run from a virtual console. Some packages are independently runnable. http://damf.sourceforge.net/ for more information.

ThreeSpace is a 3D drawing program, or modeller if you will, primarily intended for visualizing and playing with mathematical functions. It allows you to superimpose these or otherwise alter objects in 3D using them.

Wolfgang is a lightweight tool that allows users to easily create and edit Petri nets and check them against general and workflow specific net properties. Specifically, Wolfgang supports full PNML conform editing functionality of Place-Transition Nets (P/T-Nets) and Colored Petri Nets (CPN) as they are defined in the SEPIA package. Its simple and easy to use interface allows to quickly create Petri nets from scratch, edit them graphically in many ways, store and even export them as PDFs. Use Wolfgang to smoothly create the Petri net you want! A user guide and a documentation can be found under http://doku.telematik.uni-freiburg.de/wolfgang.

Demetrix is a Java-based process modelling system. The goal of the project is to develop a flexible framework for managing complex process models using Petri-Net-oriented methodologies (state-task networks and resource-task networks).

Wiki system engine that offers support for writing mathematics articles in physics, mathematics, biology, astronomy. Wiki engine is based on java servlet, java JSP technologies that offers variaty of platform independent features.

A general-purpose math library written in Java.

Vofce is a simple GUI driven graph plotting tool mainly for math students.
