Definition: A three entry vector for asymmetric population parity control. The first entry is the lower bound for population, the second is the target population, and the third is the upper bound for population.
Example:
Definition: The number of cores to use for parallel processes. A
positive integer
. ncores = 1
indicates running
in serial, while ncores > 1
indicates running in
parallel.
