Ticket sales now open: purchase a ticket

JuMP-dev 2025 will be held November 17–20, 2025 in Auckland, New Zealand.

This is the week following CPAIOR 2025, which will be held November 10–13, 2025 in Melbourne, Australia. (Melbourne is a 4 hour flight and 2 hour time difference from New Zealand.)

JuMP-dev will be co-located with the 57th ORSNZ, the Operations Research Society of New Zealand’s annual conference, which will take place November 20–21, 2025, also in Auckland, New Zealand.

Outline

The purpose of JuMP-dev is to bring together students, researchers, and practitioners with interests in the methodological, algorithmic, and software aspects of JuMP and related packages. In particular, we invite new contributors and those who have not met the core development team.

All participants will uphold the JuMP Code of Conduct.

How do I attend?

To attend JuMP-dev, you must purchase a ticket.

To request a visa invitation, please write to jump-dev-2025@googlegroups.com with the subject line Visa invitation letter.

Venue

The workshop will take place in downtown Auckland.

Talks

The first two days of JuMP-dev will be held at the GridAKL in downtown Auckland, New Zealand.

Dinner

On Monday night there will be a dinner at Good George North Wharf.

Hackathon

The hackathon on Thursday will take place in Building 201, Room 326 at 10 Symonds street.

ORSNZ 57 will be simultaneously taking place in the nearby University of Auckland Conference Centre.

Accommodation

There are a wide range of accommodation options within walking distance.

Airport transfers

The easiest way to get from the Airport to downtown is via the Sky Drive bus. Tickets are $20, and you can purchase one from the driver.

There are a variety of cheaper but non-direct and slow public transport options. You can pay for public transport in Auckland with a contactless credit card. For busses, tag on and off the reader inside the door of each bus. For trains, some stations have barriers, others have a post at the platforms.

Excursion

There will be a self-guided excursion on the Wednesday 19 November.

Option A

Assuming the weather is nice, we will plan to catch the ferry to Devonport, and walk to the summit of North Head for views over the city and harbor, followed by lunch in Devonport.

Meet at the downtown ferry terminal at 10:30.

Option B

If you want a more adventurous (but highly recommended) option, catch the ferry to Tiritiri Matangi island. This island has been cleared of all introduced pests and has many native New Zealand birds. You must book tickets in advance from explore ($110 return) and take your own food.

New Zealand entry requirements

If you require a visa, please email jump-dev-2025@googlegroups.com with the subject Visa invitation letter.

Regardless of your visa status, everyone traveling to New Zealand must complete a New Zealand Traveller Declaration. The easiest way to complete this is via the app. You must complete it no sooner than 24 hours before starting your travel. If you forget to complete the declaration prior to traveling, you may request a paper form from the flight attendants on your flight.
