LGen

An evolutionary approach to optimizing L-systems.

This is the source code for the publication Evolving L-systems in a competitive environment. A PDF version of the paper can be downloaded here.

See my website for a short write up on this experment.

To set up a simple simulation that runs for two minutes, run the following commands:

sys new
sys a *
env new
env terrain valleys 20 20 10
env init 0.5
sim new
sim density 25
sim render
sim advance-s 120

These commands initialize a 20x20 simulation environments with lindenmayer systems with the axiom * and without rules. The systems are planted every 0.5 meters in the environments. The density factor is set to 25, and the simulation runs for 120 seconds.
