June 12-16, 2017, at Sloan School of Business, Massachusetts Institute of Technology

The meetup/workshop was sponsored by the MIT Sloan Latin America Office.

The meetup is designed to serve as an opportunity for developers of mathematical optimization software within the JuMP “stack” (i.e., solvers, solver interfaces, MathProgBase, JuMP, and JuMP extensions) to meet and focus on advancing common interests. JuMP core developers will present on the internals of JuMP and solicit feedback in preparation for the release of JuMP 1.0 (targeted for July, 2017). Attendees are welcome to contribute to the JuMP stack itself or to pursue JuMP-related projects while having the JuMP developers in the same room for questions and feedback.


On Monday morning until the lunch break, Tuesday all day, and Wednesday all day, the meetup will take place in the room E62-223. This is on the second floor of the main building of MIT Sloan.

Thursday all day and Friday all day, the meetup will take place in the room E62-650. This is on the sixth floow of the main building of MIT Sloan.
