<ConsistencyModule:> neg(+Con)

   Constraints Con is negated.

Arguments
   Con                 Constraint

Type
   library(gfd)

Description

   Equivalent to 0 #= (Con)
   
   The reified constraint Con is negated.  Con must be a constraint that has
   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).
