ABSTRACT
The concept of a generation gap is linked to the notion of nonoverlapping and overlapping populations. In a nonoverlapping model parents and offspring never compete with one another, i.e. the entire parent population is always replaced by the offspring population, while in an overlapping system parents and offspring compete for survival. The term generation gap refers to the amount of overlap between parents and offspring. The notion of a generation gap is closely related to selection algorithms and population management issues.
