• Abstract summary: We introduce a new subtree tracing approach for identifying the origins of genes in the structure of individuals. We show that only a small fraction of ancestor individuals are responsible for the evolvement of the best solutions in the population.

• Abstract: This paper describes a methodology for analyzing the evolutionary dynamics of genetic programming (GP) using genealogical information, diversity measures and information about the fitness variation from parent to offspring. We introduce a new subtree tracing approach for identifying the origins of genes in the structure of individuals, and we show that only a small fraction of ancestor individuals are responsible for the evolvement of the best solutions in the population.

The proposed layout enables the size and shape of individual kernels within a convolutional layer to be evolved with a corresponding new mutation operator.
