Various types of selection methods were examined, such as random, tournament style, and fitness proportionate methods. The fitness proportionate methods that are dependent on the actual fitness score are unable to perform optimization tasks that can have a negative fitness score. Minimizing the solvation ratio allows for negative fitness scores, and thus roulette and SUS could not be used. For the performance evaluation of these two methods, 10 runs were run for polarizability and optical bandgap for a total of 20 runs. The other selection methods were run with the typical 5 runs per property, resulting in 15 total runs per selection method.
