DOLFIN is the C++ interface of the FEniCS project for the Automation of Computational Mathematical Modeling (ACMM), providing a consistent PSE (Problem Solving Environment) for solving ordinary and partial differential equations. Key features include a simple, consistent and intuitive object-oriented API; automatic and efficient evaluation of variational forms through FFC; automatic and efficient assembly of linear systems; and support for general families of finite elements.

Accord.NET provides statistical analysis, machine learning, image processing, and computer vision methods for .NET applications. The Accord.NET Framework extends the popular AForge.NET with new features, adding to a more complete environment for scientific computing in .NET.

The GOBLIN project consists of a C++ class library for a large series of graph optimization problems, GOSH, an extension of the Tcl/Tk scripting language to graph objects, and GOBLET, a graphical user interface to the library functions. GOBLET includes a graph editor and supports the standard graph layout methods.

The Linear and Non-Linear Optimization Solver (or simply the Optimization Solver) is designed to compute an optimized set of decision variables that either maximize or minimize a given objective function while also satisfying a set of arbitrary constraints. It is widely used in the field of operations research, and is a very useful business and scientific tool that will help you make an informed decision on a multitude of complex scenarios that you may encounter in your day-to-day business operations or scientific research.

ASCIIMathML is a script that converts calculator-style ASCII math notation (and many LaTeX formulas) to Presentation MathML while your Web page loads. It works with HTML and XHTML files in Mozilla/Firefox/Netscape 7+ browsers, as well as in Internet Explorer 6 with MathPlayer. For example, the solutions for the equation 'ax^2+bx+c=0' are expressed in the HTML file as '(-b +- sqrt(b^2 - 4ac))/(2a)', and display as nicely formatted MathML. The script can be easily used in wikiservers and blogs, as a rudimentary MathML editor (with instant preview), and to preview math formulas as they are typed into a Web page input area.

OPAL (Open Physics Abstraction Layer) has two main goals: to provide a high-level physics interface, and to provide an abstract interface that is independent of the underlying physics engines. Although some similar libraries focus mainly on the second goal, OPAL is more focused on the high-level physics interface. Even though the abstract interface is important for comparing physics engines or using multiple physics engines in the same application, the primary concern is giving developers a simple, powerful interface with high-level constructs.

MpNT is a multi-precision number theory library that provides a base for building cryptographic applications. It may also be used in any other domain where efficient large number computations are required. The library supports integer, modular, and floating point arithmetic with practically unlimited precision. It is both speed efficient and highly portable without disregarding code structure and clarity.

A tool that analyzes RCS files and emits an equivalent history in the form of a fast-import stream.
