We propose a stochastic implicit proximal point algorithm with variance reduction techniques where stochastic oracles are selected in two cases -- with or without replacement. The semismooth Newton methods with Armijo line search is used to solve the implicit proximal point update subproblem in each iteration. The algorithm efficiently handles the strongly-convex-strongly-concave objective function with nonsmooth regularizers and coupling linear equations, which is proved to exhibit global","authors_text":"Jiani Wang, Kehan Zhu, Yu-Hong Dai","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2026-05-22T10:50:29Z","title":"A Stochastic Implicit Proximal Point Algorithm for Solving Linearly Constrained Stochastic Minimax Problems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.23488","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:ed70fd90f86e24dc292607c7cea67243b3bd819b88e4aa546d24de9a6d59c620","target":"record","created_at":"2026-05-25T02:01:57Z","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":"8bdb21afe50cd9bd43c7f9ae0a8ab2d49424b275e3652a20e28ea9161f295a0e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2026-05-22T10:50:29Z","title_canon_sha256":"f9659de6a554a5232635a1a8a080b3571f95b800c43707f38af28f1f3900c78c"},"schema_version":"1.0","source":{"id":"2605.23488","kind":"arxiv","version":1}},"canonical_sha256":"11103df63466570878b186ec8f4d81de2d157ddc85bfda7229c925f22b80ef1a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"11103df63466570878b186ec8f4d81de2d157ddc85bfda7229c925f22b80ef1a","first_computed_at":"2026-05-25T02:01:57.339331Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-25T02:01:57.339331Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"T0KpMwkVi/yYgkulodTrtV/q6xA53VsxMfXUzXpkxeftCWnPk1GNKqsdP4gVO5dtK0Q6aWMArNnNOB1J4gxqCQ==","signature_status":"signed_v1","signed_at":"2026-05-25T02:01:57.340084Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.23488","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ed70fd90f86e24dc292607c7cea67243b3bd819b88e4aa546d24de9a6d59c620","sha256:492f567881fd68299c1e2d925e99b5667c30a29f3bd2263a7e52e0d3a93bae29"],"state_sha256":"fa4f3019dfde9ccc1842b1aa96c4e072eeb050d59cff416594d3c75b01cc9e89"}
