Open Source Mathematics Software

JGraphT is a free Java class library that provides mathematical graph-theory objects and algorithms. JGraphT supports a rich gallery of graphs and is designed to be powerful, extensible, and easy to use.

JsMath is a means of including mathematical notation in web pages. It interprets TeX code within your document and uses JavaScript, CSS and unicode fonts to typeset the resulting formulas. It works across multiple browsers and platforms, without MathML

JEuclid is a complete MathML rendering solution, consisting of: a MathViewer application, command line converters from MathML to other formats, an ant task for autmated conversion, display components for AWT and Swing and a component for Apache Cocoon

Symja - computer algebra language and Java symbolic math library. Moved to https://github.com/axkr/symja_android_library. The Android App can be found at: https://github.com/axkr/symja-example

ASCIIMathML.js: a JavaScript to convert ASCII math notation (and some LaTeX) to Presentation MathML while your webpage loads. Now also simple graphs are translates to SVG. Works with Firefox 2.0+ or with Internet Explorer 6/7+MathPlayer+Adobe SVGview.

Graidle is a project that is proposed to create a web application to generate graph diagrams. There are several classes specialized in generating histograms(horizontal),line(filled) pie and spider charts.

Web based PHP interface to communicate to Maxima computer algebra system in the server. It takes user input, send it to Maxima, and show the output back to website. It could send almost any commands including 'plot2d' and 'plot3d' to plot graphs.

Muminav started as a high specialized software component. It should be used in a project named Mumie (see project website for more info).Now it is an applet for displaying visual graphs of all kinds:<br> <br> UML, flowchcharts, E/R , genealogical trees

2020: MOVED TO https://github.com/peterjtracey/desqchess -- because it's 2020... Version 3 fork of desqchess. DESQChess will be an easy to use, easy to add on to, easy to animate chess system. Useful for apps, tablets apps, and desktop systems. Plans for other plugins include: - Add plugin to connect to animation system (web GL) - Connect to other open-source software such as Blender, illustrator, GIMP, and Vector graphic manipulation programs.

A basic GNU Octave implementation of mqtt toolkit using the paho-mqtt library

This is a map internet web service based on a huge raster maps or satellite images for tracking and monitoring the mobile objects (cars etc) using GPS.

Algebra Helper shows how signs change when moving a quantity from one side of an equation to the other. Algebra Helper is implemented in JavaScript.

JavaScript crossword puzzle builder with internationalized math capabilities. Generate unlimited layouts of user-supplied words and equations. Use file->print (to file) to save

A distributed effort to calculate pi across many computers, 9 digits at a time with minimal computer knowledge.

Automatically copies files to and from a web server.

This project deals with a new concept of the heterogeneous grid for acceleration of the numerical linear algebra computing. We design this grid with respect to maximal ratio between cost and computational power. It allows a parallelization of scientific codes with minimal programming effort. We also optimize grid concept to be less sensitive to network parameters.

A Java application that controls and simulates the flow of containers at the Rotterdam harbour.

Gamoliyas is an open source John Conway's Game of Life game totally written in DHTML (JavaScript, CSS and HTML). Uses mouse and keyboard. Very configurable. This cross-platform and cross-browser game was tested under BeOS, Linux, *BSD, Windows and other

The General Intensional Programming System (GIPSY) consists in three modular sub-systems: The General Intensional Programming Language Compiler (GIPC) ; the General Eduction Engine (GEE), and the Intensional Run-time Programming Environment (RIPE).

In the tradition of Hilbert's program we create a formal correct (checkable by a proof verifier) but readable (like an ordinary LaTeX textbook) mathematical knowledge base which is freely accessible within the internet. Logic and set theory started.

Graph visualization using hyperbolic geometry (hyperbolic trees, but also general graphs). Applications cover web site structures, topic maps, organisational charts and wikis.

Realtime bigdata tool at the bit level based on immutable AVL forest which can be run in memory or, in future versions, as a merkle forest like a blockchain. Main object is a sparse bit string (Bits) that efficiently scales up to 2^63 bits normally compressed as forest has duplicated substrings. Bits objects support reading bit, byte, short, int, or long (Java primitives) at any bit index in 64 bit range. Example: instead of building a class to hold a header and then data, represent all of that as Bits, subranges of them, and ints for sizes of its parts. Expansion ability for other kinds of compression, since Bits is a Java interface. Main functions on bits are substring, concat, number of 0 or 1 bits, and number of bits (size). All those operations can be done millions of times per second regardless of size because the AVL forest reuses existing branches recursively. Theres a scalar (originally for copy/pasting subranges of sounds) and a bit Java package. Sparse n dimensional matrix.

JavaMath is oriented toward integrating existing compute engines, such as Maple, Mathematica or GAP, into Internet accessible mathematical services.

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

MNGL (Math, Network and Graphic library) is a library which is composed by a lot of different modules to help programmers to develop their applications and softwares.
