Webrule requires iterative screening during optimization, which means that predictors cannot be screened prior to ﬁtting the model. This highlights the difﬁculty in developing screening rules for SLOPE. Our main contribution in this paper is the presentation of a ﬁrst heuristic screening rule for SLOPE based on the strong rule for the lasso.
