BSS scoring function compares favourably with BIC scoring function on acyclic networks. a Acyclic networks generated from GeneNetWeaver that are designated as the true acyclic networks. Each node corresponds to a gene. Black edges indicate activation interactions, while red edges indicate inhibition interactions. Mean distance scores computed using b BIC scoring function and c BSS scoring function for modified networks that are increasingly different from the true network in terms of edges using zero-inflated synthetic expression data. The modified networks contain from two edges up to forty different edges when compared with the true network. Each data point is the mean distance score of 100 different random modified networks that contain the same number of different edges with respect to the true network. The error bar is the standard error of the mean
