maintaining population diversity by maintaining family structures
The selection event algorithm introduced an interesting method of creating offspring from parents in a multi-generational manner with a period of fitness neutrality followed by an intense selection event. This algorithm did not have a focus on maintaining diversity in the population, so it had all of the same pitfalls as other algorithms lacking such a focus. However, due to the novel multi-generational growth structure a natural family tree is created in the population, allowing for an equally natural diversity maintenance to be implemented which does not require any artificial diversity constraints to be placed on the fitness function. Instead, diversity is maintained (and encouraged) in the population through the growth dynamics of each family.
