**Description**


The ``crossover_type`` controls what approach is employed for combining parent
genetic information to create offspring. The SCOLIB EA method supports three
forms of crossover, ``two_point``, ``blend``, and ``uniform``, which generate a
new individual through combinations of two parent individuals.
