The edit distance generalizes to languages L1,L2, where the edit distance is the minimal number k such that for every word from L1 there exists a word in L2 with edit distance at most k. We study the edit distance computation problem between pushdown automata and their subclasses. The problem of computing edit distance to pushdown automata is undecidable, and in practice, the interesting question is to compute the edit distance from a pushdown automaton (the implementation, a standard model for programs with recursion) to a regular language (the specification). In this work, we present a complete picture of decidability and complexity for deciding whether, for a given threshold k, the edit distance from a pushdown automaton to a finite automaton is at most k.","lang":"eng"}],"acknowledgement":"This research was funded in part by the European Research Council (ERC) under\r\ngrant agreement 267989 (QUAREM), by the Austrian Science Fund (FWF) projects\r\nS11402-N23 (RiSE) and Z211-N23 (Wittgenstein Award), FWF Grant No P23499-\r\nN23, FWF NFN Grant No S11407-N23 (RiSE), ERC Start grant (279307: Graph\r\nGames), and MSR faculty fellows award.","quality_controlled":"1","month":"07","oa":1,"_id":"1610","OA_type":"green","conference":{"name":"ICALP: Automata, Languages and Programming","end_date":"2015-07-10","location":"Kyoto, Japan","start_date":"2015-07-06"},"project":[{"_id":"25EE3708-B435-11E9-9278-68D0E5697425","name":"Quantitative Reactive Modeling","call_identifier":"FP7","grant_number":"267989"},{"name":"Formal methods for the design and analysis of complex systems","_id":"25F42A32-B435-11E9-9278-68D0E5697425","grant_number":"Z211","call_identifier":"FWF"},{"_id":"2584A770-B435-11E9-9278-68D0E5697425","name":"Modern Graph Algorithmic Techniques in Formal Verification","call_identifier":"FWF","grant_number":"P 23499-N23"},{"call_identifier":"FWF","grant_number":"S11407","_id":"25863FF4-B435-11E9-9278-68D0E5697425","name":"Game Theory"},{"call_identifier":"FP7","grant_number":"279307","_id":"2581B60A-B435-11E9-9278-68D0E5697425","name":"Quantitative Graph Games: Theory and Applications"},{"_id":"2587B514-B435-11E9-9278-68D0E5697425","name":"Microsoft Research Faculty Fellowship"},{"name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425","grant_number":"S 11407_N23","call_identifier":"FWF"}],"type":"conference","fulldoi":"https://doi.org/10.1007/978-3-662-47666-6_10","publication_status":"published","intvolume":"      9135","day":"01","alternative_title":["LNCS"],"doi":"10.1007/978-3-662-47666-6_10","citation":{"ama":"Chatterjee K, Henzinger TA, Ibsen-Jensen R, Otop J.
