bool Moses::WordLattice::CanIGetFromAToB	(	size_t	start,
		size_t	end
	)			const [virtual]

In a word lattice, tells you if there's a path from node start to node end.

Reimplemented from Moses::InputType.

int Moses::WordLattice::ComputeDistortionDistance	(	const WordsRange &	prev,
		const WordsRange &	current
	)			const [virtual]

Get shortest path between two nodes
