About GIDEN...

GIDEN is an interactive software environment designed to facilitate the visualization of network optimization problems, solutions, and algorithms. (Screen shots of the GIDEN software are available here.) Features of GIDEN include the following:

GIDEN is continually under development, as we extend the features of the environment and expand the solver toolkit. Currently, GIDEN includes animated solvers for the following problems: Developed at Northwestern University (Evanston, Illinois) and Systems Research (Ann Arbor, Michigan), GIDEN is targeted for use in teaching and research environments. The solvers currently included with GIDEN are customized to be used as a companion to the text:


GIDEN: This is the current version of GIDEN, which is available as a Java application. The software can be used on any Java-enabled computing platform with an available Java virtual machine (see FAQ for more info). Screen shots of the GIDEN software are available here.

GIDEN 1.0 Demo: For users who prefer a web interface, we are providing an older (October 1997) applet version of the GIDEN software. Please note that we do not support this version of GIDEN, which is substantially different from the current release.


The GIDEN project team was organized through the Industrial Engineering and Management Sciences Department at Northwestern University. The primary participants are

Collette R. Coullard       Lake Superior State University
David S. Dilworth Systems Research
Jonathan H. Owen Northwestern University, General Motors R&D

The development team gratefully acknowledges essential support for the GIDEN project from the following organizations:
