Our method synthesizes a pair of action and communication policies robust to restrictions on the number of agents allowed to communicate. To this end, we introduce a novel cost function that measures the amount of information exchanged beyond what the communication policy allows. We evaluate our approach experimentally on a range of benchmarks and demonstrate that it is capable of computing pairs of action and communication policies that satisfy the communication restrictions, if such exist.","doi":"10.24963/ijcai.2025/30","url":"https://ijcai.org/proceedings/2025/30","pdf":"https://ijcai.org/proceedings/2025/0030.pdf","markdown":"https://ijcai.org/proceedings/2025/30.md","bibtex":"https://ijcai.org/proceedings/2025/bibtex/30","volume":{"slug":"2025","title":"Proceedings of the Thirty-Fourth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2025","url":"https://ijcai.org/proceedings/2025/","year":2025,"location":"Montreal, Canada","dates":"16-22 August 2025","editors":"James Kwok","isbn":"978-1-956792-06-5","publisher":"International Joint Conferences on Artificial Intelligence Organization","doi_prefix":"10.24963/ijcai.2025"},"section":"Agent-based and Multi-agent Systems","track":"Main Track","number":30,"pages":{"first":257,"last":266},"keywords":["Agent-based and Multi-agent Systems: MAS: Multi-agent planning","Planning and Scheduling: PS: Markov decisions processes","Agent-based and Multi-agent Systems: MAS: Agent communication","Planning and Scheduling: PS: Distributed and multi-agent planning"],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
