Robustness property of various models for the gene network with nine genes. a Robustness for the gene network in Fig. 4. b Robustness for the gene network with 17 regulations (Model index: 1: netwok without any auto-regulation, 2:10: positive auth-regulation for gene Gata1, Gfi1b, Hhex, Ikaros, Myb, Nfe2, Notch1, Sox17, Sox7, respectively, 11: all nine genes have positive auto-regulation). For each model, the first bar is the mean of error; while the second bar is the variance of error
