The proposed repair operator is used to fix the solutions that violate the box constraints. More specifically, it employs a reversed correction strategy that can effectively avoid the population falling into local optimum. In addition, we integrate the proposed repair operator into two classical multi-objective evolutionary algorithms MOEA/D and NSGA-II. The proposed repair operator is compared with other two kinds of commonly used repair operators on b","authors_text":"Erik Goodman, Huibiao Lin, Shuxiang Xie, Wenji Li, Xinye Cai, Zhun Fan","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/3.0/","primary_cat":"cs.NE","submitted_at":"2015-04-01T09:07:13Z","title":"A New Repair Operator for Multi-objective Evolutionary Algorithm in Constrained Optimization Problems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1504.00154","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":"sha256:9a32e85722dad283e2791e9d25806f27d18f64f509e84b04d575a72682af202a","target":"record","created_at":"2026-05-18T02:19:44Z","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":"fe2d249deb23e1387f1f4e994a93f106befe86224eb04b435a48213124abbbc3","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-sa/3.0/","primary_cat":"cs.NE","submitted_at":"2015-04-01T09:07:13Z","title_canon_sha256":"139a2279c5f5912d6e2b19c4c67f0a3a2f29f76da7269b54de1c622bd1670b78"},"schema_version":"1.0","source":{"id":"1504.00154","kind":"arxiv","version":1}},"canonical_sha256":"0cb230792f5e8df495b37e6e958498bc9e0f096d2e7bcec71f7f60267663ba11","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0cb230792f5e8df495b37e6e958498bc9e0f096d2e7bcec71f7f60267663ba11","first_computed_at":"2026-05-18T02:19:44.424459Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:19:44.424459Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"5gc/tSUaQxQhZuP9QiNa+G9AYTbKKXJ2fdzYrDWnLnLHP8eRCWauUheCSw3P0jqaNHz8PbX0fNYcZ+8zPHNRDg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:19:44.424954Z","signed_message":"canonical_sha256_bytes"},"source_id":"1504.00154","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9a32e85722dad283e2791e9d25806f27d18f64f509e84b04d575a72682af202a","sha256:7d945d318ca28d6446fbf24666ee29e92b515eb75bc8bf86994875bf18ffb30f"],"state_sha256":"e12ec3204edf41a99fc3133219f8ad3b00de2a6235155b3e9136382fcb881088"}
