Open Source Java 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).

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/.

This project has moved. Please follow the WWW link below.

This site hosts the source code for C++ version of the Broker for SBW, NOM module, advanced simulation suite, analysis applications and model editors.

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

An easy to extend, highly graphical, easy to use 2D robot simulator specialized for path planning algorithms. Can be used in testing various robotic algorithms, and already used for comparison of path planning algorithms like RRT, RRTConnect, PRM, RboT..

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.

The goal of this project is to implement a graph layout / network visualization algorithm as a Java plugin for Cytoscape (http://cytoscape.org/), using a recently published relative entropy optimization based method, called Unified Data Representation (Kovács IA et al. Sci Rep. 2015). If you are using the plugin, please cite: Ágg B, Császár A, Szalay-Bekő M, Veres DV, Mizsei R, Ferdinandy P, Csermely P and Kovács IA (2019) The EntOptLayout Cytoscape plug-in for the efficient visualization of major protein complexes in protein-protein interaction and signalling networks, Bioinformatics 35(21):4490-4492 https://academic.oup.com/bioinformatics/article/35/21/4490/5475596 Our detailed Tutorial on the use of the plugin: https://suopte.com/entopt_2_1_tutorial_20200518.pdf A video about the version 2.1: http://suopte.com/entopt_2_1_tutorial_video.mp4 Don't hesitate to send any questions, comments or bug reports also to agg.bence {at} med.semmelweis-univ.hu.

This projects hosts the worlds fastest algorithms for the labeling of point-features. It especially looks for algorithms thar are free of constraints, applicable to many scenarios (e.g., visualization, maps...) and do not need any preprocessing.
