3/11/2022: An overview of per-instance algorithm selection, Roberto Asín, University of Concepcion
In this talk, we reviewed important concepts and problems related to Automatic Algorithm Selection. For instance, a conceptual analysis of: Per-set algorithm selection, algorithm configuration and parallel portfolio, per-instance algorithm selection, algorithm configuration and parallel portfolio, algorithm schedules and their relation with algorithm selection systems, was performed. Also, we reviewed the characteristics and evaluation metrics proposed for the two International Competitions on Algorithm Selection that were held so-far, as well as the main ideas behind the structure of the meta-solvers that participate on such tasks. We contrasted this fine-tuned systems with the more general deep-learning-based proposal of  which used Convolutional Neural Networks for performing generic algorithm selection from images created from any input file for a given problem, without the need of proposing handcrafted features.
