  abstract = {In Software Product Line Engineering (SPLE) families of systems are designed, rather than developing the individual systems independently. Combinatorial Interaction Testing has proven to be effective for testing in the context of SPLE, where a representative subset of products is chosen for testing in place of the complete family. Such a subset of products can be determined by computing a so called t-wise Covering Array (tCA), whose computation is NP-complete. Recently, reduction rules that exploit basic feature model analysis have been proposed that reduce the number of elements that need to be considered during the computation of tCAs for Software Product Lines (SPLs). We applied these rules to CASA, a simulated annealing algorithm for tCA generation for SPLs. We evaluated the adapted version of CASA using 133 publicly available feature models and could record on average a speedup of 61.8% of median execution time, while at the same time preserving the coverage of the generated array.},
