Software

Using combinatorics to solve structured linear systems of equations.

A general-purpose, extendible computing environment in which discrete mathematical objects representing real world problems can be easily manipulated and visualized.

Provides a fast graphisomorphism algorithm written in object-oriented Java using the popular yfiles graph library. The ITGI algorithm can be freely downloaded.

GDToolkit (also known as GDT) is a Graph Drawing Toolkit designed to efficiently manipulate several types of graph, and to automatically draw them according to many different aesthetic criteria and constraints.

Simplifies complicated diagrams. The package rearranges complex graph data sets into clear on-screen drawings. Core information represented by nodes and links is much easier to understand.

Software, benchmarks, events, people, bibliography, quadratic optimization.

Large scale optimization software. Solves linear, quadratic, general convex and mixed integer optimization problems. Details of products, trial downloads, licensing information, and documentation.
