(1) NonTerminationProof (COMPLETE transformation)

We used the non-termination processor [OPPELT08] to show that the SRS problem is infinite.

Found the self-embedding DerivationStructure:
Wait Left s p s End → Wait Left s p s End

Wait Left s p s End → Wait Left s p s End
by OverlapClosure OC 2
Wait Left s → Wait Right5
by OverlapClosure OC 2
Wait Left → Begin
by original rule (OC 1)
Begin s → Wait Right5
by original rule (OC 1)
Right5 p s End → Left s p s End
by original rule (OC 1)

(2) NO
