Java client, that search the hull convex of n points, with various algoritms.

This game is the generalization of the classic Battleship game to a n-dimensional grid. Rules are the same as the classic game and boats are always unidimensional, but ships can be set in a linear (1D), square (2D), cube (3D) on n-hypercubic grid.

Hypergherkin is a library for the manipulation of Real valued algebra expressions including equation simplification, symbolic integrals & derivatives. Workings can be rendered using the default presentation MathML generator or a custom alternative

Commandline Java package for computing the characteristic polynomial of a hyperplane arrangement.

ICE is a simple mathematical calculator with very useful shortcuts for Engineer: works natively with tolerance, can run Monte Carlo analysis, uses engineer notation, includes most of the day by day functions used by engineers.

Navigating Research Vessel through Ightaria, observing stars, landscape, and solving two geometrical puzzles. For High School students and other serious people hungry for Alien Geometry and Numbers.

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.

The SurfaceBuilder turns a collection of programs for implicity surface triangulation. It is usefull for any high school math student.

Impression is the flexible and extensible parser of mathematical expressions written in Java. It supports user defined operators, single or multi parameter functions and unlimited number of parameters. It is designed to use with numerical methods.

This project is a maht API based on Java

Fuzzy logic add-in for OpenOffice.org Calc. InrecoLAN FuzzyMath allows to perform ordinary arithmetic operations and use ordinary mathematical and financial functions with fuzzy numbers. Have any ideas how to improve this project - you are welcome!

The project Intergeo co-funded by the Community programme eContentplus develops an open-source library for the common file format it defines to allow developers of dynamic geometry systems to quickly integrate read support for such files.

A Kron server can assings some informations to its website. Assinging under discussion based on a mathematical model, a dynamics model.

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

Interval Analysis is a collection of interval analysis tools, allowing for robust root-finding and tracking of bounds of numerical error due to uncertain inputs and floating-point error.

This program is for generating 3-D regular grid files from scattered data. It is GUI based, reads scattered data, gets options about how to make the 3-D interpolation.

Java implementation of investment science

A java tool used for row reducing matrices of varying sizes to row echelon/row reduced echelon forms. It is intended to support basic row reduction over different fields, then expand to support other linear algebra operations and html output of working.

This project provides a set of libraries written in Java to easily manipulate Multi-Criteria Decision Aid (MCDA) concepts, especially related to outranking methods, and XMCDA files.

J³calc was initially a little project for my school but I enhanced it on and on and now it is a quite powerful calculator. It is written in Java with Swing. The sourcecode is open under the GPL 3.0 license

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.

JGP is a GUI for gnuplot (http://www.gnuplot.info/). It is made for all those who just love gnuplot but who found that organizing a large number of datasets and plots from the command line is inconvenient. JGP uses gnuplot as plotting engine.

The project aims to build a set of Java-based mathematical programs.

JBernstein is a tool implemented in Java that enables to check whether a polynomial constraint holds for all variables within their domain. It is mainly used in the verification or synthesis of cyber-physical systems where the system model is nonlinear. The tool also supports specifications in assume-guarantee style. The underlying algorithm is based on a translation to Bernstein polynomials, and several optimization techniques are implemented to ensure efficiency. Concerning performance, the tool enables to check all examples in the PVS Bernstein testsuite within a second, which can be an order of magnitude faster than some other tools such as QEPCAD or REDLOG. Although JBernstein uses double, it offers automatic error-estimation capabilities (experimental) so that the generated result is correct (the solver may return unknown when the error-estimate is too large)
