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:
[loop,numerical,local_sct]                   static Queen.search(int):boolean
                                             public static Queen.main(java.lang.String[]):void
[loop,numerical,local_bds]                   static Queen.safeMove(int,int):boolean
                                             static Queen.wrongPos(int,int,int,int):boolean
[loop,numerical,local_sct]                   static Queen.displayChessboard():void

There is at least a diverging computation for these methods:
  none

Nothing is known about these methods:
