Fully playable Java game demo illustrating basic game programming technics, such as sprite animation, pixmap fonts, time or frame related game loop, affine transformations, convolution filters, sound generation and playback...

Fuzzy numbers and basic fuzzy arithmetics (+, -, *, /, 1/x) implementation written in Java. Should be used as a library, but it also has a GUI which demonstrates its capabilities (using SWT widgets).

A Java library and set of tools to quickly and easily manipulate graphs (set of nodes and edges) and dynamic graphs. The principal trait of this library is its ability to manage (create, edit, layout, display) continuously evolving graphs. The development of this project now takes place on Github. Visit the official Graphstream website at http://graphstream-project.org

Das Horner-Schema ist ein schnelles und einfaches Verfahren, um einen Funktionswert von Polynomen an einem gegeben Wert zu berechnen. Dieses Projekt beinhält eine Facharbeit und Programmierbeispiele in Pascal und Java zum Thema.

The K.U.Leuven JCHR System is an integration of Constraint Handling Rules (CHR) and Java designed with three aims in mind: user-friendliness, flexibility and efficiency. http://www.cs.kuleuven.be/~petervw/JCHR/

The JAccumulator package brings the convenient type conversion and ad hoc composition capabilities of Javascript to Java programming structures. JAccumulator is dependent upon the Jupperware (http://jupperware.sf.net) to provide Javascript-like associative list capabilities and the convenience of easy hierarchical construction.

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)

M+ Compiler/Interpreter is a interpreter library written in Java that delivers the possibility to extend any Java application with simple scripts. Besides the usage of native datatypes and operations you can instantiate and call native Java objects.

Operations Research EXperiment Framework for Java

XMLMath evaluates mathematical, logical or textual expressions described in xml and prints the result. For example, to compute the result of 1 + 1, you would write: <add> <long value="1"/> <long value="1"/> </add>

Semantic query optimization (SQO) is the process of finding equivalent rewritings of an input query given constraints that hold in a database instance. We present a Chase & Backchase (C&B) algorithm strategy that generalizes and improves on well-known methods in the field. The implementation of our approach, the pegasus system, outperforms existing C&B systems an average by two orders of magnitude. This gain in performance is due to a combination of novel methods that lower the complexity in practical situations significantly.

The simpliZia-program implements the simplex-algorithm and is designed to help students of Operations Research to understand and learn the algorithm. This is a german project, source and program are actually written in german.

swIMP (swig-based Interfaces for Mathematical Programming) provides Java wrappers for solvers written in C or C++. The current focus is on accessing OSI-compatible linear programming (LP) solvers from the Coin-OR-project (e.g. Clp, GLPK, MOSEK, CPLEX).
