Alias: none

Argument(s): none

Default: unique_random

Required/Optional Description of Group Dakota Keyword Dakota Keyword Description
(Choose One)
Group 1 simple_random Create random initial solutions
unique_random Create random initial solutions, but enforce uniqueness (default)
flat_file Read initial solutions from file


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

  1. simple_random
  2. unique_random (default)
  3. 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.
