Context-sensitive rewrite system:
The TRS R consists of the following rules:

   U11(tt, V2) -> U12(isNat(V2))
   U12(tt) -> tt
   U21(tt) -> tt
   U31(tt, V2) -> U32(isNat(V2))
   U32(tt) -> tt
   U41(tt, N) -> N
   U51(tt, M, N) -> U52(isNat(N), M, N)
   U52(tt, M, N) -> s(plus(N, M))
   U61(tt) -> 0
   U71(tt, M, N) -> U72(isNat(N), M, N)
   U72(tt, M, N) -> plus(x(N, M), N)
   isNat(0) -> tt
   isNat(plus(V1, V2)) -> U11(isNat(V1), V2)
   isNat(s(V1)) -> U21(isNat(V1))
   isNat(x(V1, V2)) -> U31(isNat(V1), V2)
   plus(N, 0) -> U41(isNat(N), N)
   plus(N, s(M)) -> U51(isNat(M), M, N)
   x(N, 0) -> U61(isNat(N))
   x(N, s(M)) -> U71(isNat(M), M, N)

The replacement map contains the following entries:

U11: {1}
tt: empty set
U12: {1}
isNat: empty set
U21: {1}
U31: {1}
U32: {1}
U41: {1}
U51: {1}
U52: {1}
s: {1}
plus: {1, 2}
U61: {1}
0: empty set
U71: {1}
U72: {1}
x: {1, 2}

(1) CSDependencyPairsProof (EQUIVALENT)
Using Improved CS-DPs [LPAR08] we result in the following initial Q-CSDP problem.

Obligation:
Q-restricted context-sensitive dependency pair problem:
The symbols in {U12_1, U21_1, U32_1, s_1, plus_2, U61_1, x_2, U12'_1, U32'_1, PLUS_2, X_2, U21'_1, U61'_1} are replacing on all positions.
For all symbols f in {U11_2, U31_2, U41_2, U51_3, U52_3, U71_3, U72_3, U11'_2, U31'_2, U52'_3, U51'_3, U72'_3, U71'_3, U41'_2} we have mu(f) = {1}.
The symbols in {isNat_1, ISNAT_1, U_1} are not replacing on any position.

The ordinary context-sensitive dependency pairs DP_o are:
   U11'(tt, V2) -> U12'(isNat(V2))
   U11'(tt, V2) -> ISNAT(V2)
   U31'(tt, V2) -> U32'(isNat(V2))
   U31'(tt, V2) -> ISNAT(V2)
