Celebrating the first 1000 stars on GitHub

JuMP just received its 1000th star on GitHub! We will use this milestone to recap JuMP’s growth and other important milestones since its beginnings as an experimental project in 2012.

While tracking the success of an open-source project is known to be a hard problem, we have a few metrics available to us. The number of citations of the two...

An update on constraint programming in JuMP

Author: Thibaut Cuvelier (@dourouc05)

JuMP and MathOptInterface are oriented towards traditional mathematical optimization, encompassing problem classes such as mixed-integer linear programs and conic optimization. However, the MathOptInterface API is amenable to other kinds of formalism, including constraint programming.

In constrast to linear or conic programs, constraint programs typically have no objective function, but a much wider variety of constraints...

JuMP 0.21.7 is released

Formalizing a governance structure

Recently, JuMP turned eight years old. (The first commit for “Julp” was made on 10 October 2012!) It has come a long way since it’s creation as a side-project of two graduate students at MIT, and as we approach a 1.0 release, we thought it was time to formalize our governance structure.

You can find the resulting document under...

HiGHS.jl 0.1 released
