graph solutions is intelectual property of the company "Symbols & Numbers". The software was developped in Mathematica 5.0 as an addon package for Mathematica and is available for Windows, Macintosh und Linux/Unix.
The license model is based on a price in Germany for a full license currently of 1200 Euro plus taxes. The license prices include support and updates during the first year (students excluded).
Complementary we offer training courses and support contracts on request. Please contact us also, if you need an algorithm of this package in another programming language.
All licenses without a support contract are bound to one machine. In case you move to another system, we are pleased to send you a new license file. Student licenses must be renewed every two years.
Details of ordering are described on the page Order.
