Low-latency high speed hybrid framework-library for utilizing the IBM Cell processor SPE units (PS3, QS20) to carry out computational tasks. Provides some DSP tasks such as FFT and complex MAC. Thread-safe and easily extensible with new arithmetics tasks

IDL specified API for manipulating and processing CellML 1.0 and 1.1. Includes C++ implementation. Accessible from a C++ program, or from any language for which a CORBA language mapping is available Also, a Java wrapper of the API is available.

Renders cellular automata.

Cellumat3D is a tool for simulating and exploring 3D cellular automata. The simulated universe is effectively unbound and visualized using OpenGL. Currently 2-state automata similar to Conway's 2D "Game of Life" with customizable rulesets are supported.

Ceme Evaluates Math Expressions. Ceme is a free math expression parser library written in C# supporting various operators and functions. It also has the option of adding your own functions. A wrapper DLL is provided for non .NET applications.

We implement a fast version of Frommers Algorithm to calculate the focal values of a plane autonomous system over a finite field. Documentation and experiment database can be found at http://www.centerfocus.de

Centrinia is a modern mathematical modules library. It will also incorporate a Computer Algebra System.

Championship Generator produces a list of all the meetings which must occur between the participants of a championship. It supports championships where it is necessary to consider the matches at home and away.

ChaosExplorer is a C++ QT project developed to give users the ability to investigate fractals, attractors, bifurcations and other chaotic functions. The program's focus is on freedom to manipulate any possible parameter.

Graphical representation of fractals, IFS's, strange attractors,L-systems and generally chaos theory aspects.

This program is useful for visualizing bifurcations of chaotic systems. In other words, it plots the data and provides useful tools for analyzing and manipulating the data generated by chaotic systems.

Charlemagne is a versatile genetic programming application which includes a command-line client and an interactive console mode. It features built in input-output mapping support, and is user-extensible for complex fitness evaluation in Python and Lisp

This programm draws charts and diagramms out of many different also usertyped terms.

Mathematics, Chemistry and Bio-informatics semantic knowledge editor and simulation environment. It should serve as interactive science learning program or science classroom notebook and workshop.

ChemCalc is a calculator that is more oriented towards chemistry. Although starting out as a console app, it is a hope that an X11 interface will be designed at a later time.

ChemCpp is a C++ toolbox for chemoinformatics focusing on the computation of kernel functions between chemical compounds. Together with Support Vector Machines, these kernel functions find natural applications for virtual screening of molecules.

Fast search using a standard SQL on Oracle or PostgreSQL database. The package includes the database creator, loader and web application. It supports SMILES and SMARTS substructure searches, similarity search, stereochemistry.

This Chi Squared Calculator allows the user to enter any number of rows and columns, enter the observed frequencies used in the calculation, and the program will output the answer, as well as the degrees of freedom. This program runs on Python 3.2 ## BUT NO LONGER REQUIRES PYTHON to run! (Now in .exe form!) ## Sorry for the lack of floating point (Decimal) numbers support; attempting to input decimals will crash the program. Will fix soon!

I Ching offers an idea to summary the world by constructing functional mappings in finite groups. Much of ancient Chinese natural and social science grew from its concepts as root. The derived theories like "Eight Diagrams", "Five Elements" became the foundation of nearly all academic fields in acient Chinese. As a result, the theories are also the high concentration of many practical and statistical experience in China during her thousands-of-year history. This project tries to realize these algorithms with statistical programming. Overcoming the long span has important meanings. First, we can verify the validity of algorithm with big data. Second, we can put them into unprecedented wide application in the age of data. Third, the unique inspection of I Ching that linked "all the universe" open new eyes for us in thought and methodology about interdisciplinary use of data. This program is open-source for human. If you are interested in it, welcome to discuss and work together.

===== Project moved to https://github.com/fpetitjean/Chordalysis ===== Log-linear analysis is the statistical method used to capture multi-way relationships between variables. However, due to its exponential nature, previous approaches did not allow scale-up to more than a dozen variables. We present here Chordalysis, a log-linear analysis method for big data. Chordalysis exploits recent discoveries in graph theory by representing complex models as compositions of triangular structures, also known as chordal graphs. Chordalysis makes it possible to discover the structure of datasets with thousands of variables on a standard desktop computer. Associated papers at ICDM 2013, ICDM 2014 and SDM 2015 can be found at http://www.francois-petitjean.com/Research/ YourKit is supporting Chordalysis open source project with its full-featured Java Profiler. YourKit is the creator of innovative and intelligent tools for profiling Java and .NET applications. http://www.yourkit.com
