    Sorting Algorithms

    An educational demo of how sorting algorithms work.

    This is a small Java swing application that shows different sorting algorithms working on the same set of data. The user can modify the speed of execution and the type of data to sort and execute it step by step. The tooltip of each algorithm's box shows the source code that is executed and a little explanation got from wikipedia. This application is aided to computer science students who want to better understand how the algorithms work.

    TA-Lib.git: Technical Analysis Library

    Mirror of the TA-Lib project using a Git repository

    This project is intended to provide Git access to the code of the original project, TA-Lib, which uses Subversion. It is intended for system integrators wishing to use TA-Lib in their Git-managed project through Git submodules or subtrees. No actual development is being done here; all development happens in the original project.

    TEESer

    Tool for Engineering Emergent Selforganizing bEhavioR

    Teeser is a java-based integration framework for engineering emergent self-organizing behavior in distributed systems. It contains tools for analysis, tuning, macroscopic probing and simulations of distributed systems. Library of tools can be extended and everybody is encouraged to provide and share its tools with the community. The main idea is to provide application designers ability to seamlessly use tools which are helpful to design self-organizing behavior. Designers can continue to use their domain tools such as favorable simulator and by pluging it into the framework can take advantage of distributed simulations in the grid, various analyzers, optimizers (particle swarm optimization, genetic algorithms, ...). See Wiki pages for more information.
