Labeled-GA with adaptive mutation rate

In This work we propose a modified GA that assigns a unique mutation rate to each gene based on the contribution of the respective gene\´s contribution to the fitness of the individual. Although the proposed model is not "parameter free", through a number of experiments, we show that the parameters for this model are significantly insensitive to the landscape of the problems compared with the mutation rate in conventional GA, implying that this model could deal effectively with a wide range of problems the requirement to set the mutation rate empirically.
