Abstract

In the context of software product lines, there is often a need to represent graphs containing variability. For example, extending traditional modeling techniques or program analyses to variational software requires a corresponding notion of variational graphs. In this paper, we introduce a general model of variational graphs and a theoretical framework for discussing variational graph algorithms. Specifically, we present an abstract syntax based on tagging for succinctly representing variational graphs and other data types relevant to variational graph algorithms, such as variational sets and paths. We demonstrate how (non-variational) graph algorithms can be generalized to operate on variational graphs, to accept variational inputs, and produce variational outputs. Finally, we discuss a filtering operation on variational graphs and how this interacts with variational graph algorithms.
