Sorting Constraint

val sort : Fcl_var.Fd.t array -> Fcl_var.Fd.t array

sort a returns an array of variables constrained to be the variables in a sorted in increasing order.

val sortp : Fcl_var.Fd.t array -> Fcl_var.Fd.t array * Fcl_var.Fd.t array

sortp a same as sort but returns a couple (sorted, perm) where sorted is the array of sorted variables and perm is an array of variables constrained to be the permutation between a and sorted, i.e. a.(i) = sorted.(perm.(i)).

val cstr : Fcl_var.Fd.t array ->
       ?p:Fcl_var.Fd.t array option -> Fcl_var.Fd.t array -> Fcl_cstr.t

cstr a (?perm:None) sorted returns the constraint ensuring that sorted is the result of sorting array a according to the permutation perm. perm default value is None, meaning the argument is irrelevant. Raises Invalid_argument if arrays have incompatible length. Not reifiable.
