Class type

This module provides types and operations for handling consistencies. A consitency is a property obtained after a filtering operation f(s,p): given an abstract value s, and a predicate p, it computes a set s' \subseteq s such that : forall x in s, p(x) => x in s

type 'a t =

| Sat
(*
when s' = s
*)
| Unsat
(*
when s' = \emptyset
*)
| Filtered of 'a * bool
(*
filtered (s',b) : x \in s', b => p(x)
*)

type feasible =

| Unfeasible
| Maybe
| Witness of Csp.instance

val print : Stdlib.Format.formatter -> 'a t -> unit

val map : ('a -> 'b) -> 'a t -> 'b t

val bind : ('a -> bool -> 'b t) -> 'a t -> 'b t

val fold_and : ('a -> 'b -> 'a t) -> 'a -> 'b list -> 'a t

apply several filtering operation, with early termination when a unsatisfiable state is met
