Features computed in this manner are used to train algorithm performance regression models, upon which a per-run algorithm selector is then built. ...
In this new context, we show promising performance of the trajectory-based per-run algorithm selection with warm-starting. ...
The trajectory-based algorithm selection can hence be considered an extension of the per-instance algorithm selection towards a per-run algorithm selection.
