Module Interval

module Interval: sig .. end

Variable Membership to an Interval

val is_member : Var.Fd.t -> int -> int -> Var.Fd.t

is_member v inf sup returns a boolean variable which will be instantiated to 1 if v is in inf..sup and to 0 otherwise.

val cstr : Var.Fd.t -> int -> int -> Var.Fd.t -> Cstr.t

cstr v inf sup b returns a constraint ensuring that the boolean variable b is instantiated to 1 if v is in inf..sup and to 0 otherwise. Not reifiable.
