Existing program repair techniques typically aim to find any program that meets the given specification. Such “best-effort” strategies can end up generating a program that is quite different from the original one. Novel techniques have been proposed to compute syntactically minimal program fixes, but the smallest syntactic fix to a program can still significantly alter the original program’s behaviour. We propose a new approach to program repair based on program distances, which can quantify changes not only to the program syntax but also to the program semantics. We call this the quantitative program repair problem where the “optimal” repair is derived using multiple distances. We implement a solution to the quantitative repair\r\nproblem in a prototype tool called Qlose\r\n(Quantitatively close), using the program synthesizer Sketch. We evaluate the effectiveness of different distances in obtaining desirable repairs by evaluating\r\nQlose on programs taken from educational tools such as CodeHunt and edX."}],"volume":9780,"publist_id":"5819","date_updated":"2021-01-12T06:50:21Z","alternative_title":["LNCS"],"oa_version":"None","year":"2016","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","ec_funded":1,"month":"07","department":[{"_id":"ToHe"}],"day":"13","publisher":"Springer","project":[{"grant_number":"267989","_id":"25EE3708-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","name":"Quantitative Reactive Modeling"},{"call_identifier":"FWF","name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425","grant_number":"S 11407_N23"},{"grant_number":"Z211","_id":"25F42A32-B435-11E9-9278-68D0E5697425","name":"The Wittgenstein Prize","call_identifier":"FWF"}],"title":"QLOSE: Program repair with quantitative objectives","quality_controlled":"1","date_published":"2016-07-13T00:00:00Z","citation":{"ista":"D’Antoni L, Samanta R, Singh R. 2016.
