All temporal logic specifications in linear-time temporal logic (LTL) can be expressed as parity objectives. We study the qualitative analysis problem for POMDPs with parity objectives that asks whether there is a controller (policy) to ensure that the objective holds with probability 1 (almost-surely). While the qualitative analysis of POMDPs with parity objectives is undecidable, recent results show that when restricted to finite-memory policies the problem is EXPTIME-complete. While the problem is intractable in theory, we present a practical approach to solve the qualitative analysis problem. We designed several heuristics to deal with the exponential complexity, and have used our implementation on a number of well-known POMDP examples for robotics applications. Our results provide the first practical approach to solve the qualitative analysis of robot motion planning with LTL properties in the presence of uncertainty."}],"date_updated":"2023-02-23T12:25:47Z","file_date_updated":"2020-07-14T12:46:51Z","alternative_title":["IST Austria Technical Report"],"oa_version":"Published Version","type":"technical_report","page":"10","has_accepted_license":"1","doi":"10.15479/AT:IST-2014-305-v2-1","oa":1,"_id":"5426","language":[{"iso":"eng"}],"ddc":["005"],"publication_status":"published","file":[{"file_id":"5537","creator":"system","file_name":"IST-2014-305-v2+1_main2.pdf","content_type":"application/pdf","date_updated":"2020-07-14T12:46:51Z","date_created":"2018-12-12T11:54:15Z","access_level":"open_access","checksum":"730c0a8e97cf2712a884b2cc423f3919","file_size":656019,"relation":"main_file"}],"related_material":{"record":[{"relation":"later_version","status":"public","id":"1732"},{"id":"5424","relation":"earlier_version","status":"public"}]},"title":"Qualitative analysis of POMDPs with temporal logic specifications for robotics applications","date_published":"2014-09-29T00:00:00Z","citation":{"ieee":"K.
