- Statistics were calculated over 128 simulation runs, and in populations that evolved an XOR phenotype (environment AB) with and without HGT (2000 epochs). Only fit cells (fitness > 0.7) were included, resulting on an average 74% representation. Sparsity is calculated as the ratio of the number of edges to the maximum number of possible edges in a directed graph.
