AutoFolio is an algorithm selection tool, i.e., selecting a well-performing algorithm for a given instance [Rice 1976]. In contrast to other algorithm selection tools, users of AutoFolio are bothered with the decision which algorithm selection approach to use and how to set its hyper-parameters. AutoFolio uses one of the state-of-the-art algorithm configuration tools, namely SMAC [Hutter et al LION’16] to automatically determine a well-performing algorithm selection approach and its hyper-parameters for a given algorithm selection data. Therefore, AutoFolio has a robust performance across different algorithm selection tasks.
