Errorbars of selected agents’ fitness in all 50 simulations of representative PSO setups for all automatic raters. Specifically, errorbars of the fitness are demonstrated for all 20 rating iterations of the agent with the best fitness in the initial iteration, for the remaining three agents and the for the best fit agent in all iterations. a \(\hbox {R}_2\)-\(\hbox {S}_1\) rhythm. b \(\hbox {R}_2\)-\(\hbox {S}_2\) tone. c \(\hbox {R}_2\)-\(\hbox {S}_3\) rhythm. d \(\hbox {R}_2\)-\(\hbox {S}_4\) tone
