MAYBE Termination Proof

Termination Proof

by ttt2 (version ttt2 1.15)

Input

The rewrite relation of the following TRS is considered.

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

Proof

1 Termination Assumption

We assume termination of the following TRS

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