› INFORMS 2013 and JuliaOpt

First posted: Oct 12, 2013

The INFORMS 2013 Annual Meeting took place this past week in Minneapolis, and I was lucky enough to have the chance to go. Miles Lubin and I were there to present a talk based on our paper “Computing on Operations Research using Julia” (paper, slides). I’d never been to a conference like this before, so I wasn’t sure what to expect - it turned out to be a bit overwhelming! There were four time slots per day, with up to 72 sessions running during each time slot. As a result it was impossible to see anything but a small fraction of the talks. The highlights for me would have to be:

  • Meeting with the team at Forio to talk about the work they are doing with Julia, including their simulation products and their open-source Julia IDE Julia Studio
  • Seeing the Nicholson Prize contenders’ presentations on Sunday, including Vishal Gupta’s fantastic talk on data-driven robust optimization.
  • Hacking on JuMP with Miles in our hotel room.
  • Presenting the talk! We had a great, attentive audience, it was a real pleasure being there.
  • Meeting the teams from MOSEK and Gurobi, who were really enthusiastic about the work we are doing in Julia and want to be involved.
  • Finally meeting the COIN-OR team, especially Ted Ralphs.
  • Celebrating Miles winning the 2013 COIN-OR Cup!


Miles and I put a lot of thought into whats next for the burgeoning collection of optimization software and interfaces in Julia, and felt it would be appropriate to emulate the example set by JuliaStats and pull all the code together in one place. We want to go further and make sure everything works together, is well documented, and well tested. One of the end goal is to make Julia the choice for people working with optimization problems.

We’ve set up a JuliaOpt GitHub organization and a JuliaOpt website - check them out the projects, use it, report bugs, and contribute back - we’d love to have you join us.
