module VTable = Vertex.Hashtbl
module WTO : Wto.S with type node = vertex
val build_wto : pref:WTO.pref -> t -> V.t -> wto

Build a wto for the given automaton. The pref function is a comparison function used to determine what is the best vertex to use as a Wto component head. See Wto.Make for more details.

val output_to_dot : ?pp_vertex:V.t Pretty_utils.formatter -> ?pp_edge:E.label Pretty_utils.formatter -> ?wto:wto -> Stdlib.out_channel -> t -> unit

Output the automaton in dot format

val exit_strategy : t -> V.t Wto.component -> wto

Extract an exit strategy from a component, i.e. a sub-wto where all vertices lead outside the wto without passing through the head.
