LZO is a compression library which is widely used around the world. The main problem with LZO is that it is absolutely not human readable. People have done crazy stuff to get LZO to run in their language. Usually it implies inline assembly or trying to execute data which actually contains machine code. This is sick. Whoever is responsible for this sorry situation ought to be ashamed. So I'm going to deobfuscate LZO and provide a ISC implementation of this algorithm in Python and C. In addition, I will provide a textual description of the algorithm so that it can be easily ported to any programming language. I expect a severe performance degradation, but I leave optimizing for speed to other people.

This is a python implementation that handles floating points correctly,there are still some bugs but I'm working on it . The point was to work around some stuff that made no sense for floats,like 0.1+0.2 == 0.3 is false.

Formicidae is the official simulator and visualizer for the Ant-Wars competitive programming site, written in Java and SISC. The site is hosted at www.ant-wars.net.

The repository have a library to each common data structures algorithms like Doubly linked list, Generic trees, Queue, Stack... Each lib have a option to carry your custom data in elements, other cool resources.

Provides functional programming abstractions for C# including map, fold, filter functions for .NET collections, the option data type, a lazy type, a functional list type, lazy functional lists, and more. Superseded by http://sf.net/projects/sasa/

The graph fragment matching project.

Free and easy to implement algorithm that can be used for resource leveling in Gantt projects. Uses resources assignment policies, availibility calendars, tasks\' priorities, dependencies, sizings, complexity due to human communication.

Free C# library containing different math classes and algorithms

Implement a scheduling algorithm to schedule classes at a university

FunctionalJ is a library which makes it easy to use functional programming patterns in Java, such as representing functions as objects, partial function application, higher-order functions, mapping, folding, and more.

Moved to GitHub https://github.com/fedups A command-line utility to sort files. Funnel is a sort utility to sort files, large and small. It efficiently handles fixed length records and variable length records. Funnel easily handles ascii (readable) data and binary data. There are many more features in Funnel. It is easy to use and very fast. All documentation is on the Wiki.

The project will be looking at data (the intention is to begin looking at customer name/address data but this may widen over time) and ways to intelligently detect duplicates using fuzzy matching methods and algorithms.

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).

GAVS+ (Game Arena Visualization and Synthesis, Plus!) is an open-source tool which enables to visualize a broad spectrum of algorithmic games used in verification and synthesis, and offers a standard interface with utility functions to establish connection with engineering practice. It is developed by Department of Informatics (Unit 6), TU München. The tool is mainly is served for research and educational purposes. The software is released under the GNU General Public License (v3). A slightly outdated tutorial (in PDF) is included in the zip file.

GEECoP (Graphical Editor and Engine for Constrained Processes) is a tool to graphically design control-flow graphs and their associated constraints. It supports creation of Concurrent Transaction Logic formulas and validation of constrained processes.

This project is using genetics algorithms to complete scheduling tasks such as timetables for elementary / high schools etc. Currently NetBeans project with no GUI and simple HTML export.

A genetic algorithm framework to allow the evolution of synapse weights and topologies of artificial neural networks.

GAKNN is a data mining software for gene annotation data. GAKNN is built with k- Nearest Neighbour algorithm optimized by the genetic algorithm. Gene annotation datasets saved under .csv or .arff formats with Gene Ontology or FunCat categorization can use GAKNN to predict gene functions.
