The boxplot for the rank of the target epistasis in different algorithms. a The results of three basic-model datasets with one epistasis consisting of a SNP pair. b The result of the complex-model dataset, which contained three epistasis. The ‘S1-S2’ means the epistasis between SNP 1 and SNP 2 and so on. The values on the boxplot are the medians of the rank of the target epistasis among the 100 runs of simulation
