"""Example configuration file
|
|
|
|
This file illustrates how to define options and simulation parameter ranges.
|
|
It also defines the traversal order of the simulation space. As the file
|
|
extension suggests, configuration is pure python code, allowing complex
|
|
setups. Use at your own risk.
|
|
|
|
To use this example, run
|
|
python3 study.py config_example
|
|
|
|
Otherwise copy it and modify as needed. The default traversal order defined
|
|
in the nested loop of nextShape() is good for most cases, but customizable
|
|
if needed.
