Open-ended – If the process continues without reaching an obvious

This criterion can be met in a demonstration if it produces a few
innovations and is not restricted from producing more. (Capability to
reach "all possible innovations" not required.)

Right, they can change, but not in any way that conveys instructions.
Random changes are OK.
