(A) Comparison of the fitness of the genomes evolved using VEGA against the fitness of the majority rule for 5, 7 and 11. It is visually apparent that for the evolved genomes are more robust against communication noise than the majority rule. (B) Average updated state of an agent with a high fitness evolved genome with as a function of the number of neighbors in state one for . The red circles show the updated state of the agent when the initial state is one, and the red dashed line shows results for the majority rule for comparison. The empty circles show the updated state of the agent when the initial state is zero, and the black full line shows results for the majority rule. (C) Same as b, but for . It is visually apparent that the evolved genomes are more conservative than the majority rule — they require larger majorities of neighbors on the opposite state in order to change state.
