plausj a collection of checksum algorithms used to validate business keys like bank account codes or credit card numbers. It's compiled as JVM bytecode files (although it's not necessarily implemented in Java) and can be used on JRE 1.5 and later.
Implementation of Damerau-Levenshtein fuzzy string matching in Java. Returns the distance adding one point per character insert, deletion, mismatche and swap.. This is an extension of apache/commons/lang/StringUtils.getLevenshteinDistance()
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).
Currently, all existing formal tools are designed to serve as formal verifiers, using one implementation or another. JTLV is a new tool aimed to facilitate and provide a unified framework to the development of formal verification algorithms.

A Java package for pretty-printing a text by deciding where to introduce line-breaks and indentation. A Javaimplementation of Derek Oppen\'s pretty printing algorithm. It is _not_ a pretty printer for Java code, though it could be used to write one.
This is an implementation of Donald Knuth's Algorithm X ("dancing links"). This is primarily a sudoku generator and solver, though it can be used to solve other exact cover problems.
The Open Optimization for Java provides a framework and the implementation of commonly-used algorithms found in Graph Theory and Network Optimization, e.g. shortest path and postman problem.
JKalman is an Open Source Javaimplementation of Kalman filter.
Kalman filter is an efficient computational (recursive) tool to estimate the dynamic state of a process in a way that minimizes the mean of error.

OpenNeuron is a neural networks implementation written in Java. Currently supports only Kohonen Network model, but API is designed to be easily extended to model other network types. This implementation was used for face thermal pictures recognition.
This project is a highly flexible implementation of the well known bin packing algortihms: next fit, first fit, best fit, worst fit. The elements and bins may have any number of dimensions.
General purpose state observation library for Plan Old Java Objects. It enforces Model-View-Controller paradigm, has well defined API and set of ready made implementation algorithms.
Project Tokaf is an general implementation of top-k algorithm. It provides interfaces for all modules that are needed. It also features user preferences module, for computing new preferences and manipulating existing ones.
KNN-WEKA provides a implementation of the K-nearest neighbour algorithm for Weka. Weka is a collection of machine learning algorithms for data mining tasks. For more information on Weka, see http://www.cs.waikato.ac.nz/ml/weka/.
A Javaimplementation of the NEAT algorithm as created by Kenneth O Stanley. Also provides a toolkit for further experiments to be created and can provide both local and distributed learning environments.
SMSCompress is a project of investigation, development and implementation of different SMS compression techniques.
Using these techniques, SMS of more than 160 characters can be sent at only one SMS, saving money to the user ;)
Currently, all existing formal tools are designed to serve as formal verifiers, using one implementation or another. NO tool is providing a global framework to develop algorithms.
Silicis is a new formal framework for designing [verification] algorithms.
jpaul is a Javaimplementation of several
algorithms widely used in program analysis. It emphasizes
flexibility and ease-of-use and is independent of any specific
compiler infrastructure project. BSD Licence.
distDES is a Java RMI-based application which manages load balancing on heterogeneous clusters. Development will extend the theoretical initial implementation to include clustered Rainbow Table generation and encryption algorithm collision detection.
A Javaimplementation of a cubic B-spline curve smoothing function.
Allows an arbitary number of points with a variable number of dimensions to have a cubic B-spline curve "fitted". Useful in finance for analysing bond or swap yield and discount curves.
