What is GAMS?

The General Algebraic Modeling System (GAMS) is a high-level modeling system for mathematical programming problems. It consists of a language compiler and a stable of integrated high-performance solvers. GAMS is tailored for complex, large scale modeling applications, and allows you to build large maintainable models that can be adapted quickly to new situations.

GAMS-Tk

GAMS-Tk is the local GAMS-X modelling environment which enables modellers to:

• Visually generate model scenarios and sets of scenarios using existing GAMS models
• Create customized graphs across scenarios and plot series defined in a GAMS model
• Easily transfer GAMS models between GAMS-X (and hence GAMS-CGI) sites anywhere in the world
• Easily generate HTML and LaTeX model output With GAMS-Tk - no more searching through reams of listing files for outputs.

GAMS-Tk is seamlessly and transparently integrated with GAMS-CGI and the GAMS-X scripting environment. Thus, models installed and scenarios generated in GAMS-Tk are instantly viewable to anyone in the world who is connected to the web in a password-protected online environment.
