Having spent some time reading through the FAQ for comp.ai.genetic,
I've encountered a few points which I didn't quite understand.


First, I'm confused about the definition and use of the term Reproduction.

From Part I:
>     operations  such  as  crossover  or  REPRODUCTION (the propagation of
>     genetic   material   unaltered).    This   is   fitness-proportionate

From Part III:
>     REPRODUCTION:
>	  (biol, EC) The creation of a new  INDIVIDUAL  from  two  parents
>	  (sexual  REPRODUCTION).  Asexual reproduction is the creation of
>	  a new individual from a single parent.

These two descriptions seems somewhat contradictionary to me. I'm also
a bit puzzled about the term Recombination and it's relation to
Reproduction.


Secondly, the definition of ESS seems to be unsufficient.

From Part III:
>     EVOLUTIONARILY STABLE STRATEGY:
>	  A  strategy that does well in a POPULATION dominated by the same
>	  strategy.  (cf Maynard Smith, 1974)

According to Maynard Smith (``Evolution and the Theory of Games'', 1982)
it is defined as:

   " An 'ESS' ... is a strategy such that, if all the members of a
     population adopt it, no mutant strategy can invade."
