A similar technique is used for solving both Integer Programs and Constraint Programs: the problem is successively divided into smaller subproblems (branching) that are solved recursively.

Folks have been telling me they’ve noticed I’ve gotten “a lot more political” on social media this year.
Of course I have.
The circumstances have gotten nightmarishly worse, and the consequences of inaction and staying silent infinitely more obvious.
Everyone needs to get “a lot more political.”

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.
