And with Guido’s goodbye, we conclude another amazing CPAIOR. Thank you to all the speakers and attendees!
For people who couldn’t attend, we’re hoping to publish talks of the presentations where speakers allow.

In our final session for the day, we're focused on a hot topic: machine learning and mixed integer programming. Connor Lawless will start the session and tells us how to use LLMs for cold-start cutting plane separator configuration.

We start the second day of CPAIOR 2025 with an invited talk shared with ICAPS. Hanna Kurniawati talks about how the uncertainty of the real-world makes decision-making for robots challenging, and what strategies can be used to tackle it.
