A simulation run
1. Start with one learner and one adult speaker neither of
which have grammars.
2. Choose a meaning at random.
3. Get speaker to produce signal for that meaning (may
need to “invent” random string).
4. Give meaning-signal pair to learner.
5. Repeat 2-4 one hundred and fifty times.
6. Delete speaker.
7. Make learner be the new speaker.
8. Introduce a new learner (with no initial grammar)
9. Repeat 2-8 thousands of times.
