Shortest path in GAMS

Here is a presentation for a GAMS workshop. We focus on the Shortest Path LP problem. I use this model to discuss a lot of different things:

• Modeling networks in GAMS
• Sparse data structures in GAMS
• Random number generation
• Python and GAMS
• Put facility
• Visualization (Python and HTML/Javascript based) 

Example Visualization of a Shortest Path in a Network
