MiniZinc IDE-xossPB reports:"warning: model inconsistency detected before search". What does it mean? How does one go about resolving such an error?
The error means that the program that translates the MiniZinc file (.mzn) to FlatZinc file (.fzn) detects that the model is unsolvable.
A tip is to either loosen some of the domains or comment out some of the constraints and see if the error is gone. E.g. a constraint such as "constraint 1=2;" with give such an error, though it's almost never as easy as that.
