Researchers have proposed several algorithms to tackle this problem using quantitative databases with fixed item weights. However, in practical scenarios, various factors influence item weights, which may change over time to reflect real-world conditions. Moreover, traditional FWUP mining is often resource-intensive due to the large number of FWUPs generated. In this paper, we introduce the problem of mining frequent weighted utility closed patterns (FWUCP), which is a concise and lossless representation of FWUPs, from dynamic quantitative databases where item weights are adjustable. A novel algorithm, named FWUCWP, is proposed for mining FWUCPs. This algorithm employs the WUNList structure, an extension of the N-list structure, to efficiently mine FWUCPs. Additionally, three pruning strategies, WUNList subset relation pruning, maximal twu combination pruning, and enclosure-based pruning, are introduced and integrated into FWUCWP to reduce the search space. The results of experiments show that FWUCWP performs much better than the current best algorithm for mining FWUCP on sparse databases and as well as on dense databases, both in terms of runtime and scalability. data mining closed pattern dynamic quantitative databases frequent weighted utility closed pattern Full Text Additional Declarations No competing interests reported.

patterns, has garnered significant research interest. Researchers have proposed several algorithms to tackle this problem using quantitative databases with fixed item weights. However, in practical scenarios, various factors influence item weights, which may change over time to reflect real-world conditions. Moreover, traditional FWUP mining is often resource-intensive due to the large number of FWUPs generated. In this paper, we introduce the problem of mining frequent weighted utility closed patterns (FWUCP), which is a concise and lossless representation of FWUPs, from dynamic quantitative databases where item weights are adjustable. A novel algorithm, named FWUCWP, is proposed for mining FWUCPs. This algorithm employs the WUNList structure, an extension of the N-list structure, to efficiently mine FWUCPs. Additionally, three pruning strategies, WUNList subset relation pruning, maximal twu combination pruning, and enclosure-based pruning, are introduced and integrated into FWUCWP to reduce the search space. The results of experiments show that FWUCWP performs much better than the current best algorithm for mining FWUCP on sparse databases and as well as on dense databases, both in terms of runtime and scalability.\u003c/p\u003e","manuscriptTitle":"Efficient mining frequent weighted utility closed patterns with pruning strategies from dynamic quantitative databases","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-11-06 03:31:49","doi":"10.21203/rs.3.rs-6889578/v1","editorialEvents":[{"type":"communityComments","content":1},{"type":"decision","content":"Revision requested","date":"2025-11-18T03:26:19+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-11-17T02:28:50+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-11-16T18:27:40+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-11-14T05:48:50+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"322159438915015078921052483501961000982","date":"2025-11-03T06:38:29+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-11-03T05:55:50+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-11-01T13:35:13+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"143354822527073754769261245334774021602","date":"2025-11-01T13:30:34+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"229297005156110451750467708869764608152","date":"2025-10-29T19:59:49+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"58624013973197264983046618084536108805","date":"2025-10-29T18:34:27+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"162884710653651637273130707432522152154","date":"2025-10-29T17:11:52+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"100194917225734759622563136172102872658","date":"2025-10-29T14:45:32+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"324140418186291061525712358255780540392","date":"2025-10-29T11:46:16+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"147864585975870990063042213482389168891","date":"2025-10-29T05:15:00+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"335334617777174728854628314493017548993","date":"2025-10-28T08:21:44+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"20040712127942620971352981239444567058","date":"2025-10-27T19:32:15+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"16823060575672991938510385174688069307","date":"2025-10-27T14:29:10+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-10-27T14:13:26+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-06-17T10:58:53+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-06-17T10:58:35+00:00","index":"","fulltext":""},{"type":"submitted","content":"The Journal of Supercomputing","date":"2025-06-13T15:37:55+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"the-journal-of-supercomputing","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"","sideBox":"Learn more about [The Journal of Supercomputing](https://www.springer.com/journal/11227)","snPcode":"11227","submissionUrl":"https://submission.nature.com/new-submission/11227/3","title":"The Journal of Supercomputing","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"stoa","reportingPortfolio":"Springer Hybrid","inReviewEnabled":true,"inReviewRevisionsEnabled":false}}],"origin":"","ownerIdentity":"4237317e-add2-4c9c-946a-f7ab7ebdd285","owner":[],"postedDate":"November 6th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"under-review","subjectAreas":[],"tags":[],"updatedAt":"2026-01-14T20:38:38+00:00","versionOfRecord":[],"versionCreatedAt":"2025-11-06 03:31:49","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-6889578","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-6889578","identity":"rs-6889578","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
