Software refactoring under uncertainty

Mohamed Wiem Mkaouer, Marouane Kessentini, Slim Bechikh, Mel Ó'Cinnéide, Kalyanmoy Deb
2014 Proceedings of the 2014 conference companion on Genetic and evolutionary computation companion - GECCO Comp '14  
Refactoring large systems involves several sources of uncertainty related to the severity levels of code smells to be corrected and the importance of the classes in which the smells are located.  ...  Due to the dynamic nature of software development, these values cannot be accurately determined in practice, leading to refactoring sequences that lack robustness.  ...  In a real-world problem involving uncertainties, it is important to show that a robustness-unaware methodology drives the search to non-robust solutions that are sensitive to variation in the uncertainty  ...

Uncertainty Propagation through Software Dependability Models

Kesari Mishra, Kishor S. Trivedi
2011 2011 IEEE 22nd International Symposium on Software Reliability Engineering  
Systems in critical applications employ various hardware and software fault-tolerance techniques to ensure high dependability.  ...  The system is able to tolerate one hardware fault (due to one hot standby hardware server also running RB software) and one software fault.  ...  This system comprises of very complex hardware and software components. To ensure its high availability, hardware redundancy and software resiliency is employed.  ...

Object-oriented software for evaluating measurement uncertainty

B D Hall
2013 Measurement science and technology  
Hall, Metrologia, 43 (2006) L56-L61) introduced the notion of an uncertain number that can be used in data processing to represent quantity estimates with associated uncertainty.  ...  This article illustrates the uncertain-number approach using several simple measurement scenarios and two different software tools. One is an extension library for Microsoft Excel R .  ...  Greater use of software tools may offer a solution to this problem.  ...

Oracles for Testing Software Timeliness with Uncertainty

Chunhui Wang, Fabrizio Pastore, Lionel Briand
2018 ACM Transactions on Software Engineering and Methodology  
Luxembourg Uncertainty in timing properties (e.g., detection time of external events) is a common occurrence in embedded software systems since these systems interact with complex physical environments  ...  Such time uncertainty leads to non-determinism.  ...  In the presence of time uncertainty, software engineers need automated test oracles capable of determining if the non-deterministic outputs produced by test case executions are the result of time uncertainty  ...
