This repository contains a clone of SIPLIB (A Stochastic Integer Programming Test Problem Library) from Prof. Shabbir Ahmed's website isye.gatech.edu/~sahmed/siplib/. In early 2026 Georgia Tech took down this site. Many researchers expressed concerns about the removal of this library of test problems, and as a result the site was brought back online. As of March 10, 2026 the site is back online. This repository serves as a backup for this important resource in case of future disruption.
This repository is a clone of the original website, conducted via
wget -r -np -k -p https://www2.isye.gatech.edu/~sahmed/siplib/
Navigation is awkward because github doesn't display html by default, but cloning and navigating the files locally via a web browser will work. I've erred on the side of preservation by not making any modifications to the original website.
