Termination of the given GTRS could be disproven:

(0) GTRS
(1) CritRuleProof [COMPLETE, 0 ms]
(2) NO


----------------------------------------

(0)
Obligation:
Generalized rewrite system (where rules with free variables on rhs are allowed):
The TRS R consists of the following rules:

   U31(tt) -> N
   U42(tt) -> s(plus(N, M))
   U11(tt) -> U12(isNat)
   U12(tt) -> tt
   U21(tt) -> tt
   U41(tt) -> U42(isNat)
   isNat -> tt
   isNat -> U11(isNat)
   isNat -> U21(isNat)
   plus(N, 0) -> U31(isNat)
   plus(N, s(M)) -> U41(isNat)


----------------------------------------

(1) CritRuleProof (COMPLETE)
The rule U31(tt) -> N contains free variables in its right-hand side. Hence the TRS is not-terminating.

(2)
NO
