DSOL is a full featured multi-formalism, distributed simulation environment developed at Delft University of Technology (The Netherlands). DSOL has support for discrete event and for continuous modeling. Formalisms supported are event scheduling, DEVS, flow-based simulation, and continuous modeling through sets of differential equations. The first release was introduced at IEEE's Winter Simulation Conference in 2002. Since then, numerous papers and PhD dissertations have been developed, with applications in the fields of transportation and traffic, logistics, supply chain management, gaming and training, health care, and many others.

EXTE recognizes temporal expressions in a text. Temporal expressions are any references to the TIME e.g.: "today", "12th march 2006", "as soon as he woke up". This analyzer will recognize three languages: Spanish, English and French.

FunctionalCalculator is a Mathematical program, which calculates with functions and which is designed to be functional in the sense of convenience and usability. It has a desktop and a mobile edition. FunctionalCalculator has 75 User-Functions and logical / comparison operators (70 in the case of the mobile edition). The User-Functions can have arguments given by matrices, infinitely differentiable functions, complex numbers or arbitrary precision integers. Among the User-Functions you find: * The integral of f(x) from a to b * The derivative of f(x) * The Ternary Conditional * The gcd of two integers * Solve a System of Linear Equations FunctionalCalculator has a Grammar, which allows you to define you own recursive (meta) functions. The desktop edition has a functional and procedural scripting language based on this grammar and a plotter for complex functions and for real functions.

Ganzúa is a cryptanalysis tool for classical ciphers (mono and polyalphabetic) that lets the user define almost completely arbitrary cipher and plain alphabets, allowing for the proper cryptanalysis of cryptograms obtained from non-English texts.

HLM is a proof assistant for everyday mathematics, which is currently being developed. It aims for a user experience as close as possible to regular mathematical practice, and proofs which are understandable by humans with little extra effort.

IFS Tools is a set of Java applets for the interactive, graphical construction of iterated function system (IFS) fractals. Output is in the form of IFS code and graphics.

JMAT : Java MATrix tools package. Provides an easy-to-use class of matrix with MATLAB-like functions and syntax. JMAT also includes plots and histograms in 2D or 3D, an expression parser, and some statistic simulation tools.

JPlasma is a Java port of PLASMA (Parallel Linear Algebra for Scalable Multi-core Architectures)

Generates the Reverse Polish Notation (Postfix) expression form of an arithmetic expression in (Infix) form. Performs the computation of the arithmetic expression if Integers or Floating point numbers are used in the expression. Supports PEDMAS order of computation, thus, all the operators of Exponentiation, Division, Multiplication, Addition and Subtraction, as well as using Parentheses for grouping and prioritization is all handled.

This project aims to deliver a high-quality number base converter utility in Java. It will support decimal, binary, hexadecimal, octal, and a user specified base and convert between numbers of any base from 2 through 36.

D. R. Kaprekar found an interesting behaviour of four-digit number (say, 6349). Take any number; sort its digits in ascending (3469) and descinding (9643) order; subtract these (9643 - 3469 = 6174). Repeat these steps a couple of times. Surprisingly, you'

McBilliards investigates periodic billiard paths in triangles.

Draw 2D: function chart, data points chart, statistical bar chart. It's possible to combine all 3 types of chart into one. This is powerfull and easy tool, as it gives ability to manage many charts parameters. This may often compete with Gnuplot and oth

Sierpinski's triangle in various forms and languages.

A simple but effective parser for mathematical function that produces a tree to represent them.

gfit creates an interface between computational models and experimental data and provides tools for their analysis

MathToWeb is a Java-based authoring tool that converts mathematical expressions written in AMS-Latex to presentation MathML. It can be applied to single equations or entire documents containing many hundreds of equations.

Math Expression Parser 4 Java MEP4J is a high performance math expression strings parser for Java (J2SE >= 5). Compare its performance against similiar libraries and let me know your experince. The library manages the 5 operators (+, -, /, %, *) together with the following functions: - "abs" - "cos" - "sin" - "acos" - "asin" - "cosh" - "sinh" - "tan", - "tanh" - "atan" - "sqrt" - "cbrt" - "root" - "log" - "log10" - "log1p" - "exp" - "expm1" - "atan2" - "pow" The library supports variables (case insensitive), custom and pre-loaded ("e" and "pi"). Example: int num_variations = 100; int init_value = 10; MathParser mathParser = new MathParser(); mathParser.putVariable("x", init_value); mathParser.parse("2 + (7 - 5) * 3.14159 * pow(x, (12-10)) + sin(-3.141)"); for(int i = init_value; i < num_variations; ++i) { Double result = mathParser.execute(); mathParser.putVariable("x", i); }

popt4jlib is an open-source parallel optimization library for the Java programming language supporting both shared memory and distributed message passing models. Implements a number of meta-heuristic algorithms for Non-Linear Programming, including Genetic Algorithms, Differential Evolution, Evolutionary Algorithms, Simulated Annealing, Particle Swarm Optimization, Firefly Algorithm, Monte-Carlo Search, Local Search algorithms, Gradient-Descent-based algorithms, as well as some well-known network flow and other graph algorithms. A fast parallel implementation of the network simplex method, and some full-fledged parallel/distributed MIP solvers will be added in the next version. In general, emphasis is given in improving the efficiency of the algorithms in shared-memory models via java threads, since multi-core machines are so wide-spread today.

A java decision supporting application for the urban planning domain. It is designed as a desktop frontend to a Mixed Integer Programming engine. Actually it uses the GNU Linear Programming Kit (GLPK).
