Abstract-- A simulated model of plant growth and evolution
was studied. Plants start out as seeds on a 2-dimensional grid.
Plant genomes are modelled as instructions telling a plant where
to grow and where to place seeds. Energy is gained by occupying
grid space in analogy to collection of light by leaf surface area.
At the end of a generation, cells currently occupied by plants
are clered and the seeds dropped by all the plants sprout to
become the new plants. Each seed produced has a probability of
mutation to the genome it contains. The simulated plants evolve
to play a game of competitive exclusion, in which grid space is
a limited resource.
This paper tested the hypothesis that the evolved plants would
display nonlocal adaptation, i.e. that the plants would not only
