Open Source Java Frameworks

Java objects that share parts of immutable graphs. Reused subgraphs have directly or indirectly recursive Elements. Selected components get replaced by new counterparts in Context of Mirrors - translation tables. Deep copies are not involved.

The Time2 Java library provides generic time series with configurable time domains.

Interdependent Java frameworks: AMath (abstract numbers support); AFuzzy (fuzzy numbers and methods); AMathSys (flexible solvers of linear and nonlinear algebraic and differential equations); ADSM (multi-criteria ranking and grading of alternatives).

A fully customizable, extensible, scalable computational engine pluggable with various statistical and mathematical engines (R, Matlab, Octave, scilab...) The main focus and datatype considered is timeseries: the project contains also a portable and effi

Combean is a Java framework for mathematical structures and optimization algorithms. Through a set of Java interfaces and JavaBeans-based config, Combean glues optimization codes together - leading to more interoperable, adaptable and flexible solutions.

D-Cog (Declarative-Cognition) is a Java based framework for training software components (reusable, object-oriented, interface-driven components). Instead of programmed, software components are trained by example to get the expected results.

A .Net Library that lets you make full use of multi-core and multiprocessor computers. It is very efficient, and easily integrated into existing applications. It is modeled after the Parallel FX usage model, and is faster than the PFX too.

Java Api to manipulate simple on data of Matrix Type. There is lot of usefull methods like resize, insert , remove, sort and lot of other methods. Usefull methods to manipulate with diagonals. For example you can create block diagonal matrix. There is lot of usefull methods to manipulate on mathematic matrix also, like determinant , norm , minor , cofactor , solveLienarSystem , arithmetic operations also and lot more.

Digital graph 1.3 is an advanced JAVA SWING component for modelling, displaying, saving and loading graphs(using XML and XMLSchema). It is fully documented and requires jdk 1.5.x.Version 1.3 adds 9 bug fixs, 3 rengineering and 4 new features.

Expression4J (Math Expression Parser) is a java framework used to manage mathematic expression stored in String object like "f(x,b)=2*x-cos(b)" or "g(x,y)=f(y,x)*-2". Expression gramar can be define by user (add new operator or type ...)

ExpressionOasis is a java based framework for evaluating the various type of expressions like arithmatic, logic expression etc. The framework is flexible enough to define any new grammer rules or operators.

A platform which hosts battles between Fruit War robots - special java programs. The platform accepts source code as robot, and ranks all robots according to battle result. This project has been totally refined and is now hosted at http://robotypo.appspot.com

G.A.V. (Graph Algorithm Visualizer) is a tool that visualizes algorithms from graph theory. A step-by-step visualization from each different algorithm allows the user to understand the particular algorithm very easily.

The project Intergeo co-funded by the Community programme eContentplus develops an open-source library for the common file format it defines to allow developers of dynamic geometry systems to quickly integrate read support for such files.

The MOEA Framework is a free and open source Java library for developing and experimenting with multiobjective evolutionary algorithms (MOEAs) and other general-purpose multiobjective optimization algorithms. The MOEA Framework supports genetic algorithms, differential evolution, particle swarm optimization, genetic programming, grammatical evolution, and more. A number of algorithms are provided out-of-the-box, including NSGA-II, NSGA-III, ε-MOEA, GDE3 and MOEA/D. In addition, the MOEA Framework provides the tools necessary to rapidly design, develop, execute and statistically test optimization algorithms.

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.

Java OpenCL Process Virtual Machine. Spring IoC based framework for complex data analysis with OpenCL computing.

JStatCom is a software framework that facilitates the creation of JAVA programs for data based analysis tasks in various domains. It provides ways to call routines from specialized software packages, like Matlab, Gauss, Ox, and possibly others.

Framework: Project for Evolutionary Predator Prey Algorithms, used to implement an evolutionary scheme based on the developement by van Laumanns. Implement testproblems, special behaviours, environments, and other yet not known features.
