Description

The initialization_type defines how the initial population is created for the GA. There are three types:

• simple_random

• unique_random (default)

• flat_file

Setting the size for the flat_file initializer has the effect of requiring a minimum number of designs to create. If this minimum number has not been created once the files are all read, the rest are created using the unique_random initializer and then the simple_random initializer if necessary.
