<ConsistencyModule:> +ConX and +ConY

   Constraints ConX and ConY must both be true.

Arguments
   ConX                Constraint
   ConY                Constraint

Type
   library(gfd)

Description

   Equivalent to BX #= (ConX), BY #= (ConY), BX + BY #= 2
   
   The two constraints are reified in such a way that both must be true.
   ConX and ConY must be a constraints that have a corresponding reified
   form.

   ConsistencyModule is the optional module specification to give the 
   consistency level for the propagation for this constraint: 
   gfd_bc for bounds consistency, and gfd_gac for domain (generalised arc) 
   consistency. 

   This constraint is implemented using Gecode's MiniModel's rel() for
   both integer and boolean expressions, with sub-expressions/constraints
   not supported by MiniModel factored out and posted as auxiliary 
   constraints.



Modules
   This predicate is sensitive to its module context (tool predicate, see @/2).
