JuMP – recent developments

Oscar Dowson, industry representative on the ORSNZ council, presented a summary of recent JuMP developments at the 2023 ORSNZ conference. Some of the highlights are support for multiobjective optimisation, nonlinear complimentarity and many other additions and improvement. For an overview of new and improved features, have a look at Oscar’s blog post JuMP: the year in review (2023).

If you haven’t tried JuMP yet – it’s a modelling language for mathematical optimisation in the Julia programming language. I highly recommend it for your next optimisation project. There are lots of good examples and tutorials to get you started (see here).
