We explore the implications of this property on the optimization of closed-loop strategies. In particular, we focus on the decentralized LQG problem with substitutable actions. Even though the problem we formulate does not belong to the known classes of \"simpler\" decentralized problems such as partially nested or quadratically invariant problems, our results show that, under the substitutability assumption, linear strategies are optimal and we provide a","authors_text":"Ashutosh Nayyar, Seyed Mohammad Asghari","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2016-01-10T18:49:30Z","title":"Decentralized Control Problems with Substitutable Actions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1601.02250","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:9fc5c837fd2e4d335a1515acae069a3b5f58fba871b80deda33df1f55068b79b","target":"record","created_at":"2026-05-18T01:23:06Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"74834717bf0c6b43e89761f38068c9bd4a3eeeaed72bfb4c11f1fe959ff7b1da","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2016-01-10T18:49:30Z","title_canon_sha256":"bc27dd3d5905901111797821019d630cd8d54878da7cc0764365e992be01f211"},"schema_version":"1.0","source":{"id":"1601.02250","kind":"arxiv","version":1}},"canonical_sha256":"742c87b44eeb10c098ba5759a9dbdb2ccde57004c1e7fdbe8f6ff8b8e270bd81","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"742c87b44eeb10c098ba5759a9dbdb2ccde57004c1e7fdbe8f6ff8b8e270bd81","first_computed_at":"2026-05-18T01:23:06.851163Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:23:06.851163Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hYq6IFlPHGT6JOVLwVEfsi4JJse4tg25+5FAW/+tV8aQfvjIzAi+pLX9Oiq3dYQmowHBGMJxDFxAAulqnPgOAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:23:06.851568Z","signed_message":"canonical_sha256_bytes"},"source_id":"1601.02250","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9fc5c837fd2e4d335a1515acae069a3b5f58fba871b80deda33df1f55068b79b","sha256:b583fdd0a8030c7e6f0b004e03ea8e97a532af7d4e22002641313cb28b8102d6"],"state_sha256":"7c548a60b9ee3be887d7f3dc56fa6587bd6afd71a34fa46050157f919aaafcba"}
