Detailed Description

template<Automaton Aut>
struct vcsn::detail::a_star_impl< Aut >

A Star implementation of lightest automaton.

Functor taking an automaton and an a-star heuristic as parameter, applying a-star on the given automaton with the given heuristic. Return an array corresponding to the lightest 'in' transition of every state indexed by their state number.
