Detailed Description

A "node" in an acceptance formulas.

Acceptance formulas are stored as a vector of acc_word in a kind of reverse polish notation. Each acc_word is either an operator, or a set of acceptance sets. Operators come with a size that represent the number of words in the subtree, current operator excluded.
