Minimal separators of a graph

Based on the article: Generating all the minimal separators of a graph. by A. Berry, J.-P. Bordat and O.Cogis http://www.isima.fr/berry/generating.html

A set S of vertices is a minimal separator if it exists 2 distinct connected components C and D in G \ S such that each vertex of S has a successor in C and D.

#
module type G = sig

Minimal signature for computing the minimal separators

#
type t
#
module V : Sig.COMPARABLE
#
val succ : t -> V.t -> V.t list
#
val iter_succ : (V.t -> unit) -> t -> V.t -> unit
#
val fold_succ : (V.t -> 'a -> 'a) -> t -> V.t -> 'a -> 'a
#
val iter_vertex : (V.t -> unit) -> t -> unit
#
val fold_vertex : (V.t -> 'a -> 'a) -> t -> 'a -> 'a
end
#
module type MINSEP = sig
#
module G : G

Implementation of a graph

#
module Vertex_Set : Set.S with type elt = G.V.t

Implementation of a set of vertex

#
module VSetset : Set.S with type elt = Vertex_Set.t

Implementation of a set of Vertex_Set

#
val allminsep : G.t -> Vertex_Set.t list

allminsep g computes the list of all minimal separators of g.

#
val list_of_allminsep : G.t -> G.V.t list list

Less efficient that allminsep

#
val set_of_allminsep : G.t -> VSetset.t

Less efficient that allminsep

end
#
module P : functor (G : sig
include G
#
val remove_vertex : t -> V.t -> t
end
) -> MINSEP with module G = G

Implementation for a persistent graph

#
module I : functor (G : sig
include G
#
module Mark : Sig.MARK with type graph = t and type vertex = V.t
end
) -> MINSEP with module G = G

Implementation for an imperative graph. Less efficient that the implementation for a persistent graph
