Meaning of the annotations for the proof of each method:
- loop: the method seems to be part of a loop or recursion
- may_diverge: proved the existence of at least a diverging execution
- local_polyh: proved to terminate by using a local linear ranking function for the binary unfolding with polyhedra
- local_bds: proved to terminate by using local linear ranking functions for the binary unfolding with bounded difference shapes
- local_sct: proved to terminate via the size change termination principle with monotonicity constraints
- global_lex_aff_rnkfn: proved to terminate by using a global lexicographic affine ranking function
  * numerical: the ranking function uses numerical variables or fields
  * structural: the ranking function uses reference variables or fields

All calls to these methods terminate:
                                             public Alternate.Tree.():void
                                             static Alternate.Random.():void
                                             public Alternate.Tree.(Alternate.Tree,Alternate.Tree):void
[loop,structural,local_polyh]                public static Alternate.Alternate.alternate(Alternate.Tree,Alternate.Tree):Alternate.Tree
                                             public static Alternate.Alternate.main(java.lang.String[]):void
[loop,numerical,structural,local_bds]        public static Alternate.Tree.createTree():Alternate.Tree
                                             public static Alternate.Random.random():int
[loop,structural,local_bds]                  public static Alternate.Tree.copy(Alternate.Tree):Alternate.Tree
                                             public static Alternate.Tree.main(java.lang.String[]):void
                                             public static Alternate.Tree.createNode():Alternate.Tree
