To record the dependence of β ikx on other quantities, our hypergraph includes the If k − i = 1, then values of β ikx are instead computed at line 6, which does not access any other β values or the pruning mask.
our hypergraph includes the hyperedge v ikx ≺(ġ) whenever i = k −1, 0 ≤ i < k ≤ n, and With this setup, the value β ikx is the maximum score of any derivation of vertexβ ikx (a tree rooted aṫ β ikx , representing a subderivation), where the score of a derivation is the product of its leaf values.
