For Dynamic Software Product Lines (DSPLs), evaluating the quality of a feature model is important to ensure that errors in the early stages do not spread throughout the DSPL. Measures extracted from feature models have been proved to be useful in the quality evaluation of such models. However, the process used for computing the values of these quality(More)
Automatic program execution control is a demanding tool for heterogeneous environments, due to the variable availability of processors and network band-width. Issues such as load distribution have to be re-analyzed since strategies developed for homogeneous machines fail to optimize the computation time in heterogeneous networks. The nal user should not be(More)
