Ranking functions are sound and complete for proving termination and worst-case bounds of non-recursive programs. First, we apply ranking functions to recursion, resulting in measure functions, and show that they provide a sound and complete approach to prove worst-case bounds of non-deterministic recursive programs. Our second contribution is the synthesis of measure functions in non-polynomial forms. We show that non-polynomial measure functions with logarithm and exponentiation can be synthesized through abstraction of logarithmic or exponentiation terms, Farkas’ Lemma, and Handelman’s Theorem using linear programming. While previous methods obtain worst-case polynomial bounds, our approach can synthesize bounds of the form O(n log n) as well as O(nr) where r is not an integer. We present experimental results to demonstrate that our approach can efficiently obtain worst-case bounds of classical recursive algorithms such as Merge-Sort, Closest-Pair, Karatsuba’s algorithm and Strassen’s algorithm.","lang":"eng"}],"scopus_import":1,"external_id":{"arxiv":["1705.00317"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2025-06-02T08:53:47Z","publication_identifier":{"isbn":["978-331963389-3"]},"editor":[{"last_name":"Majumdar","first_name":"Rupak","full_name":"Majumdar, Rupak"},{"last_name":"Kunčak","first_name":"Viktor","full_name":"Kunčak, Viktor"}],"publist_id":"7149","year":"2017","oa_version":"Submitted Version","publisher":"Springer","quality_controlled":"1","department":[{"_id":"KrCh"}],"status":"public","intvolume":"     10427","page":"41 - 63","month":"01","date_created":"2018-12-11T11:47:39Z","project":[{"call_identifier":"FWF","_id":"25863FF4-B435-11E9-9278-68D0E5697425","grant_number":"S11407","name":"Game Theory"},{"_id":"2581B60A-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","name":"Quantitative Graph Games: Theory and Applications","grant_number":"279307"}],"related_material":{"record":[{"status":"public","id":"8934","relation":"dissertation_contains"},{"id":"7014","relation":"later_version","status":"public"}]},"language":[{"iso":"eng"}],"doi":"10.1007/978-3-319-63390-9_3","citation":{"ista":"Chatterjee K, Fu H, Goharshady AK. 2017.
