Classical approaches assume the map is fully known in advance, which falls apart the moment a box falls or a spill appears mid-shift. MAGIC instead treats traversability as uncertain and updates a shared belief about it online, using a Gaussian Markov Random Field and Gaussian Belief Propagation to spread one robot's observation to nearby unobserved cells and feed \"detour-aware\" costs into standard planners. Across benchmark tests with teams as large as 800 agents, the approach cut the actual distance traveled compared to existing methods in 96.3% of instances.\n\nThe trick is spatial inference: prior uncertainty-handling methods, contingency plans or reactive replanning, only act once a robot directly bumps into or sees an obstacle, so each robot learns the map one square at a time. MAGIC's bet is that real obstacles cluster, a puddle, a pallet of fallen stock, a blocked aisle, so one sighting can flag a whole neighborhood of unseen cells before robots drive into it. That matters most for warehouse and logistics fleets, where hundreds of robots share tight corridors and a single spill could otherwise cause a cascade of individually-discovered reroutes.\n\nIt's still a simulation result: the paper reports cost reductions, not the compute overhead of running belief propagation live across 800 agents in a real, messier warehouse. Promising math, pending a forklift.","[\"robotics\",\"path-planning\",\"multi-agent-systems\",\"algorithms\"]","2026-10-01T04:00:00.000Z","2026-10-01T13:38:48.849Z","2026-10-01T13:38:53.099Z","published",null,[],"ai",[26,27,28,29],"robotics","path-planning","multi-agent-systems","algorithms",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.40269",0,{"sections":36},[37,40,44,49,54,59,63,68,73,77,82,87,92,97],{"name":38,"slug":24,"count":39,"latest_published_at":18},"AI",5453,{"name":41,"slug":42,"count":43,"latest_published_at":18},"Security","security",805,{"name":45,"slug":46,"count":47,"latest_published_at":48},"Policy","policy",429,"2026-10-01T02:26:17.000Z",{"name":50,"slug":51,"count":52,"latest_published_at":53},"Deals","deals",298,"2026-09-30T21:00:26.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":58},"Hardware","hardware",196,"2026-09-30T13:00:00.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":18},"Science","science",159,{"name":64,"slug":65,"count":66,"latest_published_at":67},"Consumer Tech","consumer-tech",149,"2026-09-30T22:57:11.000Z",{"name":69,"slug":70,"count":71,"latest_published_at":72},"Dev Tools","dev-tools",93,"2026-10-01T02:30:48.000Z",{"name":74,"slug":75,"count":71,"latest_published_at":76},"Software","software","2026-09-30T21:41:11.000Z",{"name":78,"slug":79,"count":80,"latest_published_at":81},"Startups","startups",84,"2026-09-30T20:39:09.000Z",{"name":83,"slug":84,"count":85,"latest_published_at":86},"Gaming","gaming",51,"2026-09-30T16:24:30.000Z",{"name":88,"slug":89,"count":90,"latest_published_at":91},"General","general",50,"2026-09-30T21:37:54.000Z",{"name":93,"slug":94,"count":95,"latest_published_at":96},"Reviews","reviews",31,"2026-09-28T14:31:34.000Z",{"name":98,"slug":99,"count":100,"latest_published_at":101},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
