Several classical textbook algorithms have quite efficient average-case complexity, whereas the corresponding worst-case bounds are either inefficient (e.g., QUICK-SORT), or completely ineffective (e.g., COUPONCOLLECTOR). Since the main focus of average-case analysis is to obtain efficient bounds, we consider bounds that are either logarithmic,\r\nlinear, or almost-linear (O(log n), O(n), O(n · log n),\r\nrespectively, where n represents the size of the input). Our main contribution is a sound approach for deriving such average-case bounds for randomized recursive programs. Our approach is efficient (a simple linear-time algorithm), and it is based on (a) the analysis of recurrence relations induced by randomized algorithms, and (b) a guess-and-check technique. Our approach can infer the asymptotically optimal average-case bounds for classical randomized algorithms, including RANDOMIZED-SEARCH, QUICKSORT, QUICK-SELECT, COUPON-COLLECTOR, where the worstcase\r\nbounds are either inefficient (such as linear as compared to logarithmic of average-case, or quadratic as compared to linear or almost-linear of average-case), or ineffective. We have implemented our approach, and the experimental results show that we obtain the bounds efficiently for various classical algorithms.","lang":"eng"}],"publisher":"IST Austria","date_updated":"2020-07-14T23:05:06Z","month":"07","page":"20","date_created":"2018-12-12T11:39:23Z","alternative_title":["IST Austria Technical Report"],"pubrep_id":"619","_id":"5447","title":"Average-case analysis of programs: Automated recurrence analysis for almost-linear bounds","author":[{"full_name":"Anonymous, 1","last_name":"Anonymous","first_name":"1"},{"full_name":"Anonymous, 2","last_name":"Anonymous","first_name":"2"},{"first_name":"3","full_name":"Anonymous, 3","last_name":"Anonymous"}],"date_published":"2016-07-15T00:00:00Z","publication_identifier":{"issn":["2664-1690"]},"ddc":["000"],"year":"2016","type":"technical_report","day":"15","status":"public"}
