Yesterday afternoon, teachers downloaded and explored a piece of software called Groups and Graphs. This nice tool for creating, manipulating, and analyzing discrete graphs may also appeal to researchers; check it out at http://188.8.131.52:80/G&G/G&G.html
If you've already used Bill Kocay's software some, we'd appreciate hearing any tips, tricks, or other observations, particularly as they relate to the ongoing education or research agendas. We also welcome hearing about alternative discrete graph software, particularly freeware.
If you create files of graphs relating to the DREI99 research or education agendas which run on G&G -- or LINK (http://dimacs.rutgers.edu/~berryj/LINK.html), or other software -- please let me know. I would be happy to facilitate distributing the work amongst ourselves, or collecting them into a "library" of DREI99 software files.
