Hardware evolution system introducing dominant and recessive heredity
This paper proposes a new hardware evolution system — a new AdAM (Adaptive Architecture Methodology), that introduces dominant and recessive heredity through diploid chromosomes in order to increase genetic diversity. Dominant and recessive heredity is implemented by two techniques: one node of a tree-structured chromosome can have two sub-trees corresponding to alleles: Dominant or recessive attributes of a new pair of sub-trees is decided randomly. Simulations using the artificial ant problem show that the new AdAM is superior to the old one in adaptability and robustness in the face of a changeable environment.
