Abstract
We investigate two pathological coevolutionary behaviours, disengagement and cycling, in GP systems. An empirical analysis is carried out over constructed GP problems and the Game of Tag, a historical pursuit and evasion task. The effects of semantic bias on the occurence of pathologies and consequences for performance are examined in a coevolutionary context. We present findings correlating disengagement with semantic locality of the genotype to phenotype map using a minimal competitive coevolutionary algorithm.
