Termination Proof

by ttt2 (version ttt2 1.15)

Input

The rewrite relation of the following TRS is considered.

a(a(a(a(x0)))) → a(b(a(b(x0))))
b(a(b(x0))) → a(b(a(x0)))

Proof

1 Termination Assumption

We assume termination of the following TRS
a(a(a(a(x0)))) → a(b(a(b(x0))))
b(a(b(x0))) → a(b(a(x0)))
