    INES researchers, working in the context of the project “Models, Techniques and Tools for Software Evolution” had 2 papers accepted at CSMR 2012:

    (1) “Understanding Structural Complexity Evolution: a Quantitative Analysis”,
    Antonio Terceiro, Manoel Mendonça, Christina Chavez (UFBA) and Daniela Cruzes (NTNU)

    Abstract—Background: An increase in structural complexity
    makes the source code of software projects more difficult to
    understand, and consequently more difficult and expensive to
    maintain and evolve. Knowing the factors that influence structural
    complexity may help developers to avoid the effects of
    higher levels of structural complexity on the maintainability of
    their projects.
    Aims: This paper investigates factors that might influence the
    evolution of structural complexity.
    Method: We analyzed the source code repositories of 5 free/open
    source software projects, with commits as experimental units. For
    each commit we measured the structural complexity variation it
    caused, the experience of the developer who made the commit,
    the size variation caused by the commit, and the change diffusion
    of the commit.
    Results: Change diffusion was the most influential among the factors
    studied, followed by size variation and developer experience;
    system growth was not necessarily associated with complexity
    increase; all the factors we studied influenced at least two
    projects; different projects were affected by different factors; and
    the factors that influenced the increase in structural complexity
    were usually not the same that influenced the decrease.
    Conclusions: All the factors explored in this study should be
    taken into consideration when analysing structural complexity
    evolution. However, they do not fully explain the structural
    complexity evolution in the studied projects: this suggests that
    qualitative studies are needed in order to better understand
    structural complexity evolution and identify other factors that
    must be included in future quantitative analysis.


    (2) “On the Relevance of Code Anomalies for Identifying Architecture Degradation Symptoms”, Isela Macia(PUC-Rio), Roberta Arcoverde(PUC-Rio), Alessandro Garcia(PUC-Rio), Christina Chavez (UFBA) and Arndt von Staa(PUC-Rio).

    This work has been developed by PUC-Rio researchers,  and Christina Chavez (UFBA) co-authored it during her pos-doc at PUC-Rio.

  • Researcher from USC visits LES/UFBA

    Publicado em March 21st, 2010News, Uncategorized
    Professor Nenad Medvidović, director of USC Center for Systems and Software Engineering (CSSE),  visits the Software Engineering Laboratory (LES), UFBA from July 30 till August 21, 2010.

    The long-term, recurring theme and goal of Prof. Nenad’s research is the  development and evolution of large and complex software systems, that can be adaptable and reliableHis main research hypothesis is that an explicit focus in software architecture can tame several difficulties related to the construction and evolution of large software systems.

    During his visit, in the context of the project “Modelos, Técnicas e Ferramentas para Evolução de Software”, professor Nenad will present talks about software architecture, discuss opportunities for international cooperation and contribute to  ongoing research related to the above project.

    Professor Nenad will be the co-chair of ICSE 2011.
