General settings

This section covers all of the basic variables that describe the Avida run. You will probably not need to change these settings.

RANDOM_SEED	The random number seed initializes the random number generator. You should alter only this seed if you want to perform a collection of replicate runs. Setting the random number seed to zero (or a negative number) will base the seed on the starting time of the run -- effectively a random random number seed. In practice, you want to always be able to re-do an exact run in case you want to get more information about what happened.
POPULATION_CAP	The carrying capacity of the population (in number of organisms), removing random organisms when new organisms are born. Use 0 for no cap.
POP_CAP_ELDEST	Also applies a population cap, but removes the oldest organisms in the world.

Other general settings are described in the avida.cfg file itself: VERBOSITY, SPECULATIVE, and POP_CAP_ELDEST.
