Fig. 4: Fitness scores for the collected genetic algorithm iterations.
a–c Scores of individual objectives fi in the fitness function described in Eq. (2), represented by the scattered plots. d Overall fitness function scores comprising the weighted sum of a–c. The axes are detuning from the microring resonator cold resonance and laser scan speed, calculated from the experimental parameters of each individual: ω0 and Δω0 for the former, dω and dt for the latter. The arrows indicate the regions of optimized solutions (lower score). The color bars of the scattered plots indicate the corresponding objective function score a–c and compound fitness value d.
