Meaning of the annotations for the proof of each method:
- local_polyh: uses a local linear ranking function for the binary unfolding with polyhedra
- local_mono: uses a local linear ranking function for the binary unfolding with monotonicity constraints
- global_affrnkfn: uses a global affine ranking function with polyhedra
- numerical: the ranking function uses numerical variables or fields
- structural: the ranking function uses reference variables or fields
- loop: the method seems to be part of a loop or recursion

All calls to these methods terminate:
[loop,numerical,local_polyh]                 private static Test1.rec(int,int,int):void
                                             public static Test1.main(java.lang.String[]):void

Some calls to these methods might not terminate:
  none
There are no warnings
