The array where the Individuals in the Population are stored.
This is the maxium allowed size of the Population, if you use perlgp-run.pl to start a run. The Population class does not control the number of Individuals itself.
If migration is enabled (in the Algorithm class with EmigrateInterval and ImmigrateInterval), then this parameter determines how many Individuals move from one population to another at a time.
The directory where all the per-Individual DBM files are stored. The default is PERLGP_SCRATCH/ExperimentId.
The same as the attribute in Algorithm with the same name.
