We propose a distributed evolution strategy (DES) algorithm grounded on a proper modification to evolution strategies, a family of classic evolutionary algorithms, as well as a careful combination with existing distributed frameworks. On smooth and nonconvex landscapes, DES has a convergence rate competitive to existing zeroth-order methods, and can exploit the sparsity, if applicable, to ma","authors_text":"Chuan Chen, Chuan Luo, Qingwei Lin, Xiaoyu He, Yuren Zhou, Zibin Zheng","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.NE","submitted_at":"2022-04-09T11:18:41Z","title":"Distributed Evolution Strategies for Black-box Stochastic Optimization"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2204.04450","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:a6902d0691e41ab79019f6464b526e018ef0232545151f124b6e7348a99c6b63","target":"record","created_at":"2026-07-05T04:12:57Z","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":"194cfd5dc4c380ee81263f1cbfce2bc336960f3a9e47f539fe132f3fd602bf80","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.NE","submitted_at":"2022-04-09T11:18:41Z","title_canon_sha256":"88e16d4762811edc81260274ed1586c2d90442be3b2f6c1019eee5579bd91c07"},"schema_version":"1.0","source":{"id":"2204.04450","kind":"arxiv","version":1}},"canonical_sha256":"f1c487dfcea39177ad48210447522d2f33ea224687b509a0013afe244ff0a5fc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f1c487dfcea39177ad48210447522d2f33ea224687b509a0013afe244ff0a5fc","first_computed_at":"2026-07-05T04:12:57.381444Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:12:57.381444Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"SLqL6r93HxuhLMC4lQE3k2juSxD1Y4tQB4QfsOvfZExYAkljvL9eg8OmZfFPlR7aV1xaCwqhGJb/2wNIODpbCA==","signature_status":"signed_v1","signed_at":"2026-07-05T04:12:57.381953Z","signed_message":"canonical_sha256_bytes"},"source_id":"2204.04450","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a6902d0691e41ab79019f6464b526e018ef0232545151f124b6e7348a99c6b63","sha256:f79d2c77889f0f2bfefb1ea226b946fc7fae851bfbfea41c145712ba99d5b77b"],"state_sha256":"12086580da42fb0140e0e712e56a03a36f7a33f9c1a51f188a642a94cd21d38c"}
