Networked MARL requires all agents to make decisions in a decentralized manner to optimize a global objective with restricted communication between neighbors over the network. Inspired by the fact that sharing plays a key role in human's learning of cooperation, we propose LToS, a hierarchically decentralized MARL framework that enables agents to learn to dynamically share reward with neigh","authors_text":"Ge Li, Yaowei Wang, Yuxuan Yi, Zongqing Lu","cross_cats":["cs.MA"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2021-12-16T08:43:20Z","title":"Learning to Share in Multi-Agent Reinforcement Learning"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2112.08702","kind":"arxiv","version":2},"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:bc01128c3bffc216993f98c81444b39aaa4b768b6d6473a5a3792a4eed1f49c9","target":"record","created_at":"2026-07-05T04:33:27Z","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":"bb63e958b6c344e17d251059704db0fae57f5b9e97e1356c90b72e5de63602d0","cross_cats_sorted":["cs.MA"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2021-12-16T08:43:20Z","title_canon_sha256":"0df3255cc8aec1b468ccd81ba47255a26e3182b85ed8ce4cadb0d68aa50a9cd2"},"schema_version":"1.0","source":{"id":"2112.08702","kind":"arxiv","version":2}},"canonical_sha256":"57cb755fc1d8b090884c008d522d2dd2d50e7a62ec5413cb6c6db1bcf4ecaa3c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"57cb755fc1d8b090884c008d522d2dd2d50e7a62ec5413cb6c6db1bcf4ecaa3c","first_computed_at":"2026-07-05T04:33:27.666969Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:33:27.666969Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"gQ4lwJoU4TeM1UalgnhqkYE4B0I3TLhw5NgPr5cC7mLmTnJOVbvYgzo3XE2l6h7xS8ErMAjpYg043TbQi4rhDA==","signature_status":"signed_v1","signed_at":"2026-07-05T04:33:27.667428Z","signed_message":"canonical_sha256_bytes"},"source_id":"2112.08702","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:bc01128c3bffc216993f98c81444b39aaa4b768b6d6473a5a3792a4eed1f49c9","sha256:0b61c8f6ab61265ee6258605eb18e204c2ca30d8208af375cb6dc27aff3c139b"],"state_sha256":"96ef0cf7f73646b415e80afa95a8297d16395c1d5418a82cc7022ace1dc181f8"}
