Evaluate an arithmetic expression is as simple as: Double result = new DoubleEvaluator().evaluate("(e^3-1)*sin(pi/4)*ln(pi^2)"). But Javaluator provides you with much more ... Key features: - Functions support, including variable argument count. - Constants support: e, pi, etc ... - Variables support: Example sin(x) for x = pi/4. - Highly configurable: Reduce the built-in operator or function sets, define your own brackets. - Extensible: Define your own grammar, or extends the existing one. - Localizable: Define localized names for functions or constants. - Syntax check - Small footprint: 26kB, no additionnal library required. - Fully documented Please visit the project site to learn more : http://javaluator.fathzer.com If you use Javaluator in your product, we will be happy to add a link to your product in the Javaluator web site.

This project provides an interface to Java expression evaluator software. It does not itself provide expression capabilities but instead provides a common interface.

An online judge system to judge the ACM-ICPC programming contests.

The goal of this fractal renderer is to enable intricate images to be created with maximum control over the results. To this end, it supports multiple layers, many fractal types (including user – defined equations) and different ways of rendering.

Kandid generates images using genetic algorithms. In a simulated evolution surprising images can be found calculated with Lisp expressions, Textures, Iterated Function Systems, Linear Cellular Automata, Voroni diagrams, Lindenmayer Systems and POVray

D. R. Kaprekar found an interesting behaviour of four-digit number (say, 6349). Take any number; sort its digits in ascending (3469) and descinding (9643) order; subtract these (9643 - 3469 = 6174). Repeat these steps a couple of times. Surprisingly, you'

Draws Kentonian spirals.

KeplerDB is a temporal database to store time/value entries where the type of value could be integer, float/double, boolean and string. KeplerDB is dedicated to be scalable and to create clusters of server allowing the user to analyse and store massing amount of data to monitor systems like computers, clusters, building and captors or financial systems like markets and accounts. The user can use KeplerDB to make data analysis on enormous amount of data (statistics and modelling).

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.

This software is to generate kicker playing schedules that should be as fair as possible. There are the following hard constraints: - Each match consists of 4 players, with 2 teams of 2 players each. - All players participating at the whole schedule will be included in the same number of matches. The following optimization objectives are being regarded: - Each player should be scheduled for each table position equally often. - All combinations of team-mates should happen equally often. - All combinations of opponent players should happen equally often. - The leisure times of each players between its participated matches should be distributed as equally as possible.

The Kinship Algebra Modeller is a suite of java applications that assist development of an algebra to describe a given kinship terminology, and to support models and simulations of social processes based on relating people using this algebra.

Klang is a stack-based, post-fix calculator language.

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

This small library implements the Koch curve, snowflake and anti-snowflake like a Shape to be used like any other Java shape. You can test the library by compiling the test applet in Files.

Generic implementation of pluggable Condorcet voting methods

Kontinuum is a calculator program that enables the user to calculate all probabilistic aspects of the Kontinuum RPG system, especially the dice rules.

Tool for performing special mathematic operations needed for cryptography on your mobile. Useful for cryptography-lectures.

A language modeling tool kit written in Java for natural language processing applications. It can handle character-by-character modeling of unknown words, language model combination, comparison, and evaluation, as well as a number of smoothing techniques

LExAu: Learning Expectations Autonomously. Library for on-line data driven statistical machine learning.

LOOP (Language Object Oriented Parallel) is a visual programming language project dedicated to creating a full suite of components for simulation of hierarchical dynamical systems in discrete time.

A rich client to analyse data from a liquid-feedback (http://liquidfeedback.org/) instance, for now it's a 3d graph explorer to inspect the delegations. It's an application based on the eclipse platform (indigo). To be precise its a directed weighted multi graph browser in 3d.

LTI-Lib is an object oriented computer vision library written in C++ for Windows/MS-VC++ and Linux/gcc. It provides lots of functionality to solve mathematical problems, many image processing algorithms, some classification tools and much more...

A lambda calculus interpreter for android.

The Latin Square Toolbox contains software tools for efficiently generating Latin squares and counting their transversals with various user-configurable options. This open source release aims to help educate folks on Latin squares and their important applications to cryptography. This version contains three tools: 0. Latin Square Generator (LSG) 1. Latin Square Transversal Counter (LSTC) 2. Latin Square Property Checker (LSPC)

A Java application enabling users to create, edit, and view sports or competition results. In addition, there are facilities to view league tables and other statistical information based on the results.
