2 Other Forms of Lineage Selection

Other implementations of lineage selection could allow further control of genetic diversity via genetic lineages. Here, two other selection schemes are described that could be used with genetic lineages to accomplish different objectives. These three methods, the one used here and the two above, modify the standard tournament selection scheme to force competition and breeding across lineages, force competition within lineages but breeding across lineages, and finally to force competition and breeding from within the same lineage. The more restrictive the method becomes, the more the algorithm will need to consider the potential drawbacks. However, particularly with the last method, these forms of selection could be considered very efficient implementations of more familiar models of similar and dissimilar mate selection and distributed models.
