Selection Methods

In the following table is shown the selection methods that you can be chosen to configurie the evolutionary algorithms skeletons (except CHC).

These methods can be used in selection section of the cofiguration file and in the configuration of the migration operator.

In the CHC skeleton, the selection methods are not optional. In the selection section of the CHC configuration file, you must choose the parameter (percent of population that will restarted) of replace method and the diverge operator that will used to restart the population whenever convergence is detected.

Intra-population Operators

Intra-population operators:

Id.	Name	Parameters*	Others
0	Crossover	Application probability	HUX in CHC
1	Mutation	Application probability	bit-flip in CHC
2	Hybrid operator	Application probability	only in newGASA
3-	Other operators	Application probability	-

Inter-population Operators

Intra-population operators are the operators that are applied between sub-populations. Currently, the skeletons only have got a single inter-population operator, the migration operator. In order to configure this operator, you must define:

• operator number (0)
• operator rate
• number of individuals
• selection method (and its parameters) of individual to send
• and replace method (and its parameters) of individual to send .
