Frequently failed onboarding postpones developers' development schedule, and the evolutionary progress of open source projects. To mitigate developers' costly efforts for onboarding, we propose a ranking model NNLRank (Neural Network for List-wise Ranking) to recommend projects that developers are likely to contribute many commits. Based on 9 measured project features, NNLRank learns a ranking function (represented by a neural network, optimized by a list-wise ranking loss function) to score a list of candidate projects, where top-n scored candidates are recommended to a target developer. We evaluate NNLRank by 2044 succeeded onboarding decisions from GitHub developers, comparing with a related model LP (Link Prediction), and 3 other typical ranking models. Results show that NNLRank can provide developers with effective recommendation, substantially outperforming baselines.","PeriodicalId":121436,"journal":{"name":"Proceedings of the 40th International Conference on Software Engineering: Companion Proceeedings","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127095079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They rather require teams of robots that collaborate and interact to perform a desired mission. They must also be used in contexts in which only partial knowledge about the robots and their environment is present. To ensure mission achievement, robotic applications require the usage of planners that compute the set of actions the robots must perform. Current planning techniques are often based on centralized solutions and hence they do not scale when teams of robots are considered, they consider rather simple missions, and they do not work in partially known environments. To address these challenges, we present a planning solution that decomposes the team of robots into subclasses, considers complex high-level missions given in temporal logic, and at the same time works when only partial knowledge of the environment is available.","PeriodicalId":121436,"journal":{"name":"Proceedings of the 40th International Conference on Software Engineering: Companion Proceeedings","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131899251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing APR approaches use unit tests or constraint solving to find and validate program patches. We propose Canonical Search And Repair (CSAR), a program repair technique based on semantic search which uses a canonical form of the path conditions to characterize buggy and patch code and allows for easy storage and retrieval of software patches, without the need for expensive constraint solving. CSAR uses string metrics over the canonical forms to cheaply measure semantic distance between patches and buggy code and uses a classifier to identify situations in which test suite executions are unnecessary-and to provide a finer-grained means of differentiating between potential patches. We evaluate CSAR on the IntroClass benchmark, and show that CSAR finds more correct patches (96% increase) than previous semantic search approaches, and more correct patches (34% increase) than other previous state-of-the-art in program repair.","PeriodicalId":121436,"journal":{"name":"Proceedings of the 40th International Conference on Software Engineering: Companion Proceeedings","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131135982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, when it is applied to discover flaws in software systems, most of the respective verification tools lack scalability due to the state-space explosion problem. Abstraction technique is useful in reducing the state space of systems. It maps a concrete set of states to a smaller set of states that is actually an approximation of the system with respect to the property of interest. Predicate abstraction [3] is one of the most often used methods for attaining a finite abstract model from a concrete program which is often even an infinite state system. With predicate abstraction, a finite set of predicates, which determines the precision of the abstraction, is selected to keep track of certain facts about the program variables. The model obtained via predicate abstraction is an over-approximation of the original program. Thus, spurious paths may exist when an insufficient set of predicates are considered.","PeriodicalId":121436,"journal":{"name":"Proceedings of the 40th International Conference on Software Engineering: Companion Proceeedings","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123256376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several program repair techniques follow a Generate-and-Validate work-scheme: programs are iteratively sampled from within a predefined repair search space, and then checked for correctness to see if they constitute a repair. In this poster, we propose an enhanced work-scheme, called Generate-Validate-AnalyzeErr, in which whenever a program is found to be incorrect, the error trace that is the evidence of the bug is further analyzed to obtain a search hint. This hint improves the sampling process of programs in the future. The effectiveness of this work-scheme is illustrated in a novel technique for program repair, where search hints are generated in a process we call error generalization. The goal of error generalization is to remove from the search space all programs that exhibit the same erroneous behavior. The aim of this poster is to present our vision of the future of program repair, and trigger research in directions that have not been explored so far. We believe that many existing techniques can benefit from our new work-scheme, by focusing attention on what can be learned from failed repair attempts. We hope this poster inspires others and gives rise to further work on this subject.","PeriodicalId":121436,"journal":{"name":"Proceedings of the 40th International Conference on Software Engineering: Companion Proceeedings","volume":"227 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122616418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To do this, we participated as volunteers in the HistoryCal project. We used the case study research method to investigate technique application and community participation.
