It tracks how those early, practical ideas fed into the AGM framework, the formal theory that became the field's dominant model for belief revision. The authors work through Doyle and London's original taxonomy category by category, showing how each one evolved, survived, or got replaced once AGM's formal guarantees took hold. True to its title, the paper delivers both a survey and an implementation roadmap, though it stops short of actual working code, which the authors point to as a job for a follow-up paper.\n\nBelief revision sits underneath any system that has to update what it 'knows' without breaking consistency, from 1980s expert systems to today's knowledge bases and reasoning agents. AGM theory has spent decades as an elegant but hard-to-implement standard, and the gap between its formal guarantees and actual code is a familiar complaint in AI research. A paper that connects the two properly, instead of just restating one side, is more useful than most literature reviews in this space.\n\nIt is still preparatory work, a foundation for the engineering paper still to come. But unlike surveys that only gesture at future implementation, this one includes the roadmap itself, not just a promise of one.","[\"belief revision\",\"ai research\",\"knowledge representation\",\"agm framework\"]","2026-08-18T04:00:00.000Z","2026-08-18T05:09:59.429Z","2026-08-18T05:10:11.267Z","published",null,[24],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"The source's own title is 'A Survey and an Implementation Roadmap for Belief Change,' meaning the roadmap is presented as part of this paper — but the draft's framing (and its closing line, 'this is a survey promising a future roadmap, not the roadmap itself') asserts the opposite, that the roadmap is deferred to a future follow-up paper; verify against the actual paper whether the roadmap is included here or genuinely future work, and correct the framing\u002Fclosing line accordingly.","resolved","ai",[32,33,34,35],"belief revision","ai research","knowledge representation","agm framework",[37],{"name":38,"url":39},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2608.14567",0,{"sections":42},[43,47,51,56,61,66,71,76,81,85,90,95,100,105],{"name":44,"slug":30,"count":45,"latest_published_at":46},"AI",3293,"2026-08-20T04:00:00.000Z",{"name":48,"slug":49,"count":50,"latest_published_at":46},"Security","security",435,{"name":52,"slug":53,"count":54,"latest_published_at":55},"Policy","policy",210,"2026-08-19T09:32:27.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Hardware","hardware",140,"2026-08-19T18:25:42.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Consumer Tech","consumer-tech",95,"2026-08-18T16:05:00.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Science","science",90,"2026-08-19T18:41:02.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Software","software",73,"2026-08-18T07:51:50.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":18},"Dev Tools","dev-tools",69,{"name":86,"slug":87,"count":88,"latest_published_at":89},"Startups","startups",47,"2026-08-19T19:13:46.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"General","general",33,"2026-08-18T22:18:13.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":106,"slug":107,"count":108,"latest_published_at":109},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
