Genex v1.0.1-beta Genex.Support.Genealogy View Source

Implementation of a genealogy tree.

We use the Genealogy tree to model the history of the population from it's initialization to the end of the algorithm. The tree itself is a directed Graph implemented using libgraph. Genealogy is tracked in a population struct, so you can access the genealogy anytime through the current population. Any function in the libgraph library will work on a genealogy

An edge emanates from parent and is incident on child. Mutants are considered new chromosomes, so their lineage starts with a single parent.

To produce visualizations of the Genealogy of an evolution, you'll have to export the tree to a DOT file and use a third-party visualization tool.
