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.

NOTE: Yacas and yagy development has moved to github. The new repositories are located at https://github.com/grzegorzmazur/yacas and https://github.com/grzegorzmazur/yagy . The mailing list has been moved over to https://groups.google.com/forum/#!forum/yacas . The downloads section at sourceforge will be kept up to date for the foreseable future. Yacas is an easy to use, general purpose computer algebra system. It uses its own programming language designed for symbolic as well as arbitrary-precision numerical computations. The system comes with a library of scripts and extensive documentation. Yagy (http://sourceforge.net/p/yagy) provides full yacas experience wrapped in a simple and intuitive graphical interface.

Java/XML toolkit for research using Bayesian networks and other graphical models of probability (exact and approximate inference, structure learning, etc.)

Calculate the number of solutions to place n queens on an n*n chess board, without any queen attacking each other. Options allow using rooks instead of queens, disabling knight attacks and setting the minimum distance between queens.

A program to calculate and create lists of possible variations (permutations) and selections (combinations) of a given set of elements. Creating the cartesian product of two sets is also possible.

An EDM calibration baseline is used to derive specific instrument errors of the electronic distance measurement (EDM) unit of a total station. EDMFit is a simple adjustment tool to estimate the EDM calibration parameters (addition constant and/or scale parameter). The adjustment process is according to ISO 17123-4. The parameters are checked for significance, to avoid an overestimation. Based on two classical hypothesis testing, EDMFit provides a reliable outlier detection. For uncertainties budgeting, EDMFit makes use of Monte-Carlo simulations and supports different distribution function: - Uniform distribution, - Triangular distribution and - Gaussian (normal) distribution. For refractive index determination, the application supports the following models: - Barrel and Sears (1939), - Edlen (1953, 1966), - Owens (1967), - IAG (1999) and - Ciddor (1996, 2002). The results of the adjustment are reported in a template-based and valid HTML5/CSS3 report.

A Java application for drawing dynamic mathematics features (as geometric figures, dynamic algebra) and for creating dynamic animations using geometrics tools. You can also export the figures to Latex2e pstricks, mfpic environment or JPEG, WMF, EPS image

A cross-platform, text-interpreting calculator written in the Java programming language. Runs on any computer with Java 6 or higher installed. Functions much like a Ti-84, but without the graphing utility.

Logo command and construct library for Java. Intended as a tool for teaching novice programmers the Java language and object orientation.

Mark Six Analyst is a database of Hong Kong Lottery or so-called Mark Six. It provides a tool of various statistics method to show relationships between data and forecasts.

Parallel Spectral Deconvolution is a multithreaded ImageJ plugin for spectral image deblurring.

Draw 2D: function chart, data points chart, statistical bar chart. It's possible to combine all 3 types of chart into one. This is powerfull and easy tool, as it gives ability to manage many charts parameters. This may often compete with Gnuplot and oth

It's a program that plots Bode diagrams with an excellent precision. In this new version it's very easy to provide the function to plot thanks to a simply graphic interface in style "what you see is what you got". A smart output window allows to plot more than one graph at the same time, and easily compare them. The plotted graphs can be exported as images, in various format. Language supported: italian. Next version probably will include other languages; certainly english will be the first. This is a beta version, so please report any bug if you find something wrong! Your help will be very appreciated! NEWS! asymptotic diagram plotting function added! the function is in beta test, and does not support complex factor.

The Decision Deck project aims at developing a generic decision aid platform composed of modular "software components". These software components implement the common functionalities of a large range of multiple criteria decision aid methods. This

DragMath is a drag and drop equation editor in the form of a Java applet. Once an expression is created the user can convert it into a variety of different linear syntax for mathematics, including MathML, LaTeX, Maple, Maxima or any user defined style. PLEASE NOTE: active code development has moved to GitHub. https://github.com/maths/dragmath

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

OpenForecast is a package of general purpose, forecasting models written in Java that can be applied to any data series. No knowledge of forecasting is required. Using this package, the most appropriate algorithm for your data will be selected.

+++DISCLAIMER+++ The project is still currently in beta, thus have bare functionality, and possible bugs. Anyone who can spare time and lend a helping hand as a beta-tester is very appreciated. Contact the author for more information. +++INTRO+++ STEMCalc IV is a simple, yet powerful, console-programmed calulator written in Java, performing one calculation with two numbers max at a time and other various functions. +++STORY+++ This is the fourth edition of the previously abandoned student project STEMCalcR. The project has never seen the light of day due to various bugs and lack of usability, even after attempts at reviving the project in the forms of STEMCalcR2 and R3Boot editions. Determined, not giving up, me, one of the original co-authors of STEMCalcR, has brought to you STEMCalc IV, the swiss knife of mathematics. I am determined to drive this project further, turning it into a powerful program , more than just your average calculator.

Sphaerica is an interactive spherical geometry computer software. You can create complex geometric constructions in spherical geometry with this software. It supports orthogonal, stereographic and gnomonic projections to display your construction. It also has a built in scripting language for automated constructions.

A text editor for maths. Simple algebra should be faster and more intuitive to perform on a computer than on paper and should look like maths. Write small fragments in plain text; perform simple click-and-drag algebra with the mouse; and explore more involved algebra through keyboard shortcuts. When done, save as plain text files or export to LaTeX and HTML.
