Open Source Algorithms

A framework for learning from a continuous supply of examples, a data stream. Includes classification, regression, clustering, outlier detection and recommender systems. Related to the WEKA project, also written in Java, while scaling to adaptive large scale machine learning.

An open source workbench for chemo- and bioinformatics built on the Eclipse Rich Client Platform (RCP).

The Progressive Graphics File (PGF) is an efficient image file format, that is based on a fast, discrete wavelet transform with progressive coding features. PGF can be used for lossless and lossy compression. It's most suitable for natural images. PGF can be used as a very efficient and fast replacement of JPEG 2000.

Python library for a fast and flexible graph data structure.

A C++ library for clipping polygons.

MobileMath is a software written by using J2ME technolology. It turns mobile into calculator supporting many operations such as : evaluate expression, plotting, differentiate & integrate expression... It can run on any mobiles supporting Java.

A very lightweight advanced terrain-rendering and 3D map rendering system. Minimal dependencies: OpenGL, SDL. It's distrib in 2-3 separate modules: 1. the C++ implementation of the terrain- and/or surface- rendering Algorithms I have developed: both a multithread and a non-multithread variant is relaeased. 2. Seme as at point 1. , but with a road-network rendering and collision-detection module I wrote before. It also adds some trees at the top of the terrain. (multitread vesion not released yet) 3. Seme as point 2.. Multithread terrain-rendering, roads on it, and vehicles to go around. The most important part is terrain-rendering. The Algorithm at the heart of it features my first and second theorem abut polygonal surface approximation. It took something like 2 years to develop it. It's technically a view-dependent, continuous dynamic level-of-detail rendering algorithm. Main features are simplicity and documentation. Does easily a 4k x 4k terrain, but also much more.

PHP Polar Tools is a set of PHP classes for the parsing and management of Polar Heart Rate Monitor data.

Plantra-Trajectory Planning is a software to rebuild surfaces from cloud points, featuring shaded 3D visualization and path planning for robotics paths. It uses Voronoi diagram, Cyrus-Beck clipping, Delaunay triangulation and B-Splines.

PyPlayground is an environment for developing algorithms involving movement in a space of up to three dimensions using Python.

SenseRank Sys: - builds the dictionaries (multidim matrices) of words’ values; - for the set utterance in certain language builds a figure in multidimensional space (in the matrix space) of values (visual schema), which is topological view of sense

A Java API for using suffix trees with natural language and an Eclipse/SWT-based GUI for suffix tree visualization using Graphviz.

The Watermarks is a java library for images and text watermarking fingerprinting and tamper-proofing. The supported carrier formats for a watermark are JPEG and PDF. The project also aim to build a test environment to evaluate robustness of implemented a

Efficiently create compact, highly customizable tree layouts - Based on Walker's algorithm with enhancements suggested by Buchheim, Jünger, and Leipert the software builds tree layouts in linear time. I.e. even trees with many nodes are built fast. Downloads are available at https://sourceforge.net/projects/treelayout/files/. For detailed documentation look at the TreeLayout web site http://treelayout.sourceforge.net/. Development for TreeLayout has moved to https://github.com/abego/treelayout/.

API Java de visualisation et d'interaction dans le domaine des graphes.

Libgxl++ is a library based on the libxml++ and libxml2 to provide a complete and efficient API to parse and manipulate the GXL format.

Openminer, as a data mining engine, is developed on java for analysis of dataset with the methods of data mining. By making use of openminer, we could discovery the knowledge which interests us but hides in the raw data.

breve is a free, open-source 3D multi-agent simulation package designed for simulating decentralized systems and artificial life.
