We present an illustrated introduction to Query By Example (QBE), an exciting new addon of VIATRA. QBE is a tool that helps you write queries simply by selecting model elements in your favorite editor. This automatic feature is intended to help users who are learning the VIATRA Query Language and/or are unfamiliar with the internal structure of the modeling language (metamodel) they are working with.Read More
This year's task was a simplified version of the Class Responsibility Assignment problem, where methods and attributes have to be assigned to classes in a way that the assignment is optimal with respect to certain software metrics. Our team has solved this problem using VIATRA's rule-based design space exploration framework (VIATRA-DSE), and our solution was awarded the first prize from the nine submitted solutions. The solution was authored by Gábor Szárnyas and András Szabolcs Nagy. The source is available on Github.
The corresponding research was supported by the MTA-BME Lendület 2015 Research Group on Cyber Physical Systems (original article).
