Parallel Evolutionary Algorithms

The need to improve the scalability of Genetic Algorithms (GAs) has motivated the research on Parallel Genetic Algorithms (PGAs), and different technologies and approaches have been proposed. This project will focus on investigating, designing and evaluating new technologies (e.g., Hadoop, Spark) for PGAs in the context of Software Engineering.

Software Development Effort Estimation

Software development effort is considered the dominant cost of software projects, thus effort estimation is a critical activity for planning and monitoring software project development and for delivering the product on time and within budget. The research projects related to this topic regard the definition and empirical evaluation of multi-objective search-based approach for building novel estimation models.

Data Imputation Methods for Software Engineering Tasks

Historical software project datasets have been utilized together with machine learning algorithms for various software engineering classification tasks. Unfortunately, the missing values in datasets have negative impacts on the estimation accuracy of such approaches and therefore, could lead to inconsistent results. This project will focus on investigating, designing and evaluating the effectiveness of data imputation methods in the context of Software Engineering.

Software Defect Prediction

Software defect prediction has been an active subject of research since the 1990s. However, despite many proposals for different fault prediction techniques, only our previous study has used the information available from the testing phase in order to improve the performance of predictive models. This project will investigate other metrics useful to improve the accuracy of the estimates.
