The rewrite relation of the following TRS is considered.
U12(tt) | → | s(plus(N,M)) | (1) |
U22(tt) | → | plus(x(N,M),N) | (2) |
U11(tt) | → | U12(tt) | (3) |
U21(tt) | → | U22(tt) | (4) |
plus(N,0) | → | N | (5) |
plus(N,s(M)) | → | U11(tt) | (6) |
x(N,0) | → | 0 | (7) |
x(N,s(M)) | → | U21(tt) | (8) |
t0 | = | U22(tt) |
→ | plus(x(U22(tt),U22(tt)),U22(tt)) | |
= | t1 |
