bibo_abstract:
- When a new mutant arises in a population, there is a probability it outcompetes
the residents and fixes. The structure of the population can affect this fixation
probability. Suppressing population structures reduce the difference between two
competing variants, while amplifying population structures enhance the difference.
Suppressors are ubiquitous and easy to construct, but amplifiers for the large
population limit are more elusive and only a few examples have been discovered.
Whether or not a population structure is an amplifier of selection depends on
the probability distribution for the placement of the invading mutant. First,
we prove that there exist only bounded amplifiers for adversarial placement-that
is, for arbitrary initial conditions. Next, we show that the Star population structure,
which is known to amplify for mutants placed uniformly at random, does not amplify
for mutants that arise through reproduction and are therefore placed proportional
to the temperatures of the vertices. Finally, we construct population structures
that amplify for all mutational events that arise through reproduction, uniformly
at random, or through some combination of the two. @eng
