Performance of PriorPC against σ for various αs in terms of AUROC. All edges have a true prior. Gaussian noise is added to all priors with various standard deviations σ. The different colors represent the result for various αs. The performance of PC is plotted in green and with full squares for comparison. For small standard deviations, PriorPC performs better than PC-lite. This effect is not seen for large standard deviations since most priors are flipped
