OpenSIMPLY is an open source project for simulation modeling in Delphi, Lazarus, Free Pascal. Download OpenSIMPLY at opensimply.org The project is free computer simulation software based on discrete-event approach. OpenSIMPLY is a science software with very high simulation performance. So, the simulation results can be obtained much faster. The project is suitable for people with any modeling experience, and can be used for both science and education. Some application of this modeling software are: - traffic simulation - network simulation, - emergency and evacuation ways simulation and much more. This simulation tool runs in Windows and Linux, on 32-bit and 64-bit platforms, as a GUI or console (terminal) application. Write the model only once, simulate anywhere.

RADLib is a graphics library. It was written in order to help developers design graphics applications easily and quickly. The library is available for .NET, Java, Delphi, Kylix.

The main goal of this project was developing phase-field simulations of lithium dendrite growth with FEniCS programmed in Python. The problem was based in the grand potential-based model of Zijian Hong and Venkatasubramanian Viswanathan (https://doi.org/10.1021/acsenergylett.8b01009) . Some simpler examples were developed before for a first approach with FEniCS: heat equation and combustion model.

OpenAxiom is an open source Computer Algebra System. It offers an interactive environment, an expressive programming language, a compiler, a large set of mathematical libraries of interest to researchers and practitioners of computational sciences.

Arageli is a C++ library for computations in arithmetic, algebra, geometry, linear and integer linear programming. Arageli provides routines and classes that support precise, i.e. symbolic or algebraic, computations.

This is module for basic computation with floating point numbers. Numbers can have very wide mantissa for good precision, for realize "arbitrary-precision arithmetic". Module was adapt for BCB and MSVC compilers. Russian comments.

Java library for parsing and evaluating math expressions. Javadoc is available at http://bracer.sourceforge.net/javadoc/ P.S. This library depends on Apache Commons Math, so don't forget to include commons-math-2.2.jar to your project.

Calculates how much time and money you need to win in the lottery. It uses multiple gthreads and gtk2 to sort 1 to 50 numbers until the user wins. Asking for the cost and time beetwin games, it calculates if you or your grandchildren will be rich.

This project (CvHMM) is an implementation of discrete Hidden Markov Models (HMM) based on OpenCV. It is simple to understand and simple to use. The Zip file contains one header for the implementation and one main.cpp file for a demonstration of how it works. Hope it becomes useful for your projects.

This program allows to draw diagrams with chart library, that can be used with dialog applications, based on the RC files designers (such as FbEdit for example). This is the one of the fastest way to create window application with visual design methods, and implement into it an ellegant and flexible chart, that can be choosen from four different diagram kinds (if you edit code and use it in your projects). The source code chart library by Lothar Schirm is based on the consolidated solutions from FireFly Designer by Paul Squires. FB Chart Designer shows the complete example of connection those mentioned solutions to achieve thiny file and less code project. It makes more simply to analyze code and provides faster implementation of rebuilted chart library. Chart drawing method is based on "windows.bi" FreeBasic library (Windows API framework).

The Library is for Finite Transforms such as the Number Theoretic Transform (NTT) and Finite Radon Transform (FRT). Current modules include NTTW for NTTs with high resolution (microsecond) timing, basic array and imaging. The transforms are optimised for performance.

Graph Package (GPack) is a solution for developing simple graphics in Delphi environment. GPack includes 2 components TGraph & TGraph3D which help users to create 2D/3D graphic applications in an easiest and quickest way.

GraphLab provides a rich environment for researchers in Graph Theory field. The project page has moved to http://graphlab.sharif.ir

Graficas 2D is an opensource library for plotting 2D functions. It's compatible with .NET Framework and Mono

Hypergherkin is a library for the manipulation of Real valued algebra expressions including equation simplification, symbolic integrals & derivatives. Workings can be rendered using the default presentation MathML generator or a custom alternative

Integration routine to be employed in evaluation of high dimensional integrals arising from problems in statistical mechanics, more specifically the partition function of classical Heisenberg spin-chains, and its resulting derivatives.

Math4J is a java library with an object-oriented design of some mathematical ideas: functions, primality, complex numbers, etc. It also consists of some utility methods and classes for mathematical constructions.

This project gives a mathematical parser for converting a simple string expression into a result which can be managed for using in other calculations, all in Java. Using a couple lines of code, you'll be able to parse complex arithmetic expressions efficiently. This library is powered by Dijkstra's Shuting-yard algorithm. The library has no dependencies with other external libraries. Dependency <dependency> <groupId>com.google.code.mathparser-java</groupId> <artifactId>mathparser-java</artifactId> <version>1.0.0</version> </dependency> Expressions supported (Mar/09/2013) - Arithmetic operations. Working on (Mar/09/2013) - Geometrical functions support
