Sensitivity to the number of outer steps. We choose NoTears-L1 as the base algorithm, and study our algorithm’s sensitivity to the number of outer steps (X-axis). We test on a 30-node ER graph with 500 samples: the algorithm’s performance is much noisier with respect to changing numbers of outer steps. Thus, in practice, we need to carefully select the number of outer steps for each different dataset
