In case you haven’t been following this virtual thread:
- Bill Idsardi‘s six-page paper “A simple proof that Optimality Theory is computationally intractable” appeared in the latest issue of LI (vol. 37, 271-275).
- AndrĂ¡s Kornai has a one-page reply (“Is OT NP-hard?”) on ROA.
- Idsardi has a three-page rejoinder (“Misplaced optimism”), also on ROA.
- Update: And another by Kornai (“Guarded optimism”).
This is exactly the sort of thing that should be happening on ROA (and, I would hope, also here on phonoloblog).
