I ask the interval or
syntax-based group what they do in case of irreducible graphs, and
the answers are either fall back to iterative methods, or use node
splitting, or give up.
no science here.
Some science, perhaps. Elimination boils everything down to composition (ab),
alternation (a|b), and iteration (a*). There's a Tarjan paper that tells
how to parse an arbitrary directed graph and get an equivalent regexp.
Alas, I can't find the reference. It was someplace I don't read much,
perhaps JACM, something like 1980-85.
