3 years ago Let's name this something like "minimal φ head side".
The thing that ended up italics in the above list is supposed to be (a b) (c) with an asterisk after "a" and one after "c".
Switching to acute accents for this comment to avoid further italics
Something that the three-word list didn't make clear is that we want left- and right-headed minimal φs to be able to co-occur. So for (ω ω) (ω ω), we want:
LL: (ώ ω) (ώ ω) LR: (ώ ω) (ω ώ) RL: (ω ώ) (ώ ω) RR: (ω ώ) (ω ώ)
And just to reiterate, only words in a minimal φ can be accented. Not allowed: {ώ...}, (...φ...ώ...), etc.
Theoretially, the thought behind this is that children in level-skipping configurations, and/or nodes lower than one of their siblings, are "adjoined", so they can't be the head of their parent. Equivalently (I think), if we interpret "head" as "accented", then running AccentAsHead on any of these structures should give 0 violations.

A function that takes the output of GEN and for each tree in the candidate set, returns several trees...
addMinimalPhiHeads(ptree): returns {all trees q such that q is like ptree except that every minimal phi has a head labeled either at its left edge or its right edge}
Nick Kalivoda's specifications: every minimal φ is marked by Gen as either being left-headed or right-headed. So for three words, just looking at the minimal φ's,:
(a b c) (a b c) (a) (b c) (a) (b c) (a b) (c) (*a b) (c*) (a) (b) (c*)
NOT generated: (a b* c)
