(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 b b b a a a b End → Wait Left b b b a a a b End

Wait Left b b b a a a b End → Wait Left b b b a a a b End
by OverlapClosure OC 2
Wait Left b b → Wait Right9
by OverlapClosure OC 2
Wait Left → Begin
by original rule (OC 1)
Begin b b → Wait Right9
by original rule (OC 1)
Right9 b a a a b End → Left b b b a a a b End
by original rule (OC 1)
