This module contains additional algorithms, genes and chromosomes which are somehow not standard. The main reason for this division is the desire to keep the io.jenetics.base module as small as possible.
The io.jenetics.ext.moea package contains classes and data structures, which allows the optimization of multi-object problems.
The io.jenetics.ext.engine contains classes, which allows the creation of adapting evolution streams. Depending on the actual population statistics, it is possible to change the parameters for the underlying evolution Engine.
