GSL shell offers an interactive user interface that gives access to the GSL collection of mathematical functions. It is based on the powerful and elegant scripting language Lua. GSL shell is not just a wrapper over the C API of GSL, but offers a much more simple and expressive way to use GSL. The objective is to give the user the power to easily access GSL functions without having to write a complete C application. It also has a powerful module to produce plots or almost any kind of graphics based on data or functions.
TSPSG is intended to generate and solve "travelling salesman problem" (TSP) tasks. It uses the Branch and Bound method for solving. Its input is a number of cities and a matrix of city-to-city travel costs. The matrix can be populated with random values in a given range (which is useful for generating tasks). The result is an optimal route, its price, step-by-step matrices of solving, and a solving graph. The task can be saved in an internal binary format and opened later. The result can be printed or saved as PDF, HTML, or ODF. TSPSG may be useful for teachers to generate test tasks or just for regular users to solve TSPs. Also, it may be used as an example of using the Branch and Bound method to solve a particular task.
FroZenLight interrelates line arts, mathematics, and cryptography. Circular shaped mirrors which are arranged in a grid-like manner reflect a light ray according to the reflection law of geometric optics. While random positions of the light source produce chaotic reflection patterns, it is possible to position the light source so that beautiful symmetric reflection patterns are created.
JAME is an application for creating fractals and other graphics artifacts. It is written in the Java language, with some native code to accelerate encoding of videos and images. It has a real-time, multi-threaded graphics engine with layers, filters, effects, a lot of formulas, and parameters. JAME supports operations such as continuous zoom of Mandelbrot and Julia sets, rotation, and color shifting. JAME has also advanced features such as networked computation and scripting. You can take photos of your fractals or record movies from your exploration paths. Photos and movies are stored in a database to be rendered in high resolution and exported to a file. JAME can be extended by plug-ins which provide fractals, formulas, filters, effects, and more.
Social Networks Visualizer (SocNetV) is a flexible and user-friendly tool for the analysis and visualization of Social Networks. It lets you construct mathematical graphs with a few clicks on a virtual canvas, load networks of various formats (GraphViz, GraphML, Adjacency, Pajek, UCINET, etc), or create a network by crawling all links in a Web page. The application can compute basic network properties, such as density, diameter, and distances (shortest path lengths), as well as more advanced structural statistics, such as node and network centralities (i.e. closeness, betweenness, graph), clustering coefficient, etc.
trojuhelnik is a general solver for triangles. It computes all possible solutions for a triangle that is specified by an arbitrary triple of the following elements: sides, angles, altitudes, medians, angle bisectors, area, radius of circumscribed and inscribed circle, sum a+b, perimeter and difference of the angles. All other elements, triangle visualization, and graphs of elements dependencies are also available.
