The most basic objective is the reachability objective, where a target set must be eventually visited, and the more general parity objectives can model all omega-regular specifications. For such objectives, the computational analysis problems are the following: (a) qualitative analysis that asks whether the objective can be satisfied with probability 1 (almost-sure winning) or probability arbitrarily close to 1 (limit-sure winning); and (b) quantitative analysis that asks for the approximation of the optimal probability of satisfying the objective. For general POMDPs, almost-sure analysis for reachability objectives is EXPTIME-complete, but limit-sure and quantitative analyses for reachability objectives are undecidable; almost-sure, limit-sure, and quantitative analyses for parity objectives are all undecidable. A special class of POMDPs, called revealing POMDPs, has been studied recently in several works, and for this subclass the almost-sure analysis for parity objectives was shown to be EXPTIME-complete. In this work, we show that for revealing POMDPs the limit-sure analysis for parity objectives is EXPTIME-complete, and even the quantitative analysis for parity objectives can be achieved in EXPTIME.","lang":"eng"}],"external_id":{"arxiv":["2511.13134"]},"publication_status":"published","project":[{"name":"Formal Methods for Stochastic Models: Algorithms and Applications","grant_number":"863818","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","call_identifier":"H2020"},{"_id":"4029cfc7-b034-11f1-9e55-88ab2ff3b6ee","grant_number":"COE12","name":"Bilateral Artificial Intelligence (Chatterjee)"}],"acknowledgement":"This work was partially supported by the ANRT under the French CIFRE Ph.D program in collaboration between NyxAir and Paris-Dauphine University (Contract: CIFRE N° 2022/0513), by the French Agence Nationale de la Recherche (ANR) under reference ANR-21-CE40-\r\n0020 (CONVERGENCE project), by Austrian Science Fund (FWF) 10.55776/COE12, and by the ERC CoG 863818 (ForM-SMArt) grant.","department":[{"_id":"KrCh"}],"issue":"43","year":"2026","page":"36146-36154","volume":40,"publication_identifier":{"issn":["2159-5399"],"eissn":["2374-3468"]},"date_updated":"2026-09-16T07:28:33Z","citation":{"chicago":"Asadi, Ali, Krishnendu Chatterjee, David Lurie, and Raimundo J Saona Urmeneta. “Revealing POMDPs: Qualitative and Quantitative Analysis for Parity Objectives.” In <i>Proceedings of the AAAI Conference on Artificial Intelligence</i>, 40:36146–54.
