Springer, Heidelberg , http: Over the past few years, there has been a growing interest in automating refactoring activities based on metaheuristic approaches. Parameter control is a promising area of research, but mainly unexplored in SBSE. From Figure 2, the predominance of papers with 2 authors is observed through the years. We just have to add all the components of all the k elements to get the elementary landscape decomposition of coverage x. One aspect related to the publications is the type of venue where the works are published. Does the approach produce programs that are a greater design distance from the original than those produced by the source-to-source refactoring approach?

Of particular interest is the distinction between parameter tuning and parameter control: Landscape theory provides a formal framework in which combinatorial optimization problems can be theoretically characterized as a sum of a special kind of landscape called elementary landscape. We investigated five parameters: But is there some way to exploit this linearity? An infrastructure and its potential impact.
Among the 15 most cited publications, 10 have at least one of the most prolific authors shown in Table 9. Does the proposed approach produce programs of higher quality than a source-to-source refactoring approach in terms of metrics values? The segments are described on Section 2.
Fraser their ago in the current population. In Table 1, for each class in the case study and test budget , we report the relative coverage averaged out of 15 runs of the worst and best configurations. A genetic programming approach to automated software repair.
However, to make SBSE really usable in practice, no knowledge of search algorithms should be required from practitioners who want to use it, as such knowledge is gls specialized and might not be widespread. If we are given two solutions, and C has a common subsolution, then the solutions for subgraph A and B can aagp exchanged.
This preponderance of proceeding publications compared to journal articles is also observed in the Computer Science field as a whole . The meaning of these levels corresponds to fuzzy subsets of U, e. Typically, we would like for the size of set C to be minimal.
Springer, Heidelberg 8. Tuning gl2s algorithms for real-world applications: The former deals with how to choose parameter values before running a search algorithm. Only one fixed search budget i.
As a solution, we proposed a multi-level refactoring approach as a combination of code and design improvement tools to refactor a program based on both its design and source code.
Furthermore, strong static code dependence between source code entities such as relationships between methods and attributes disallow many refactorings. A ball of radius k is the set of all the solutions lying at Hamming distance lower or equal to k. The authors then make two key innovations: This would reduce the dire threats to external validity coming from over-fitting the parameter tuning.
A final analysis in Table 1 regards the cumulative growth acquired inwhich was of We also use in the following the term Ti to refer to the binary string composed of the elements of the i-th row of matrix T.

But random mutations cause exactly what one would expect: It is not the length that matters, it is how you control it. The review period was followed by a moderated online discussion. Section 3 shows the bibliometric analysis for the four categories analysed Publications, Sources, Authorship, and Collaboration in the period. Assume a graph can be broken into subgraphs A, B, C, where C is a separator.
Negative test cases that cause the original program to fail are needed.
gire Aside general software engineering venues, as the top 3, journals of specific areas are also present, including software testing and requirements engineering. In this experiment, it is assumed that the users are familiar with the systems under investigation and know the existing design problems in these systems. An interesting example of this occurs in the work of Weimer and Forrest [?
