Termination w.r.t. Q of the following Term Rewriting System could be proven:

Q restricted rewrite system:
The TRS R consists of the following rules:

a(a(x1)) → b(b(b(x1)))
b(b(x1)) → c(c(c(x1)))
c(c(c(c(x1)))) → a(b(x1))

Q is empty.

Q restricted rewrite system:
The TRS R consists of the following rules:

a(a(x1)) → b(b(b(x1)))
b(b(x1)) → c(c(c(x1)))
c(c(c(c(x1)))) → a(b(x1))

Q is empty.

We use [27] with the following order to prove termination.

Knuth-Bendix order [24] with precedence:
trivial

and weight map:

c_1=28
b_1=44
a_1=67
dummyConstant=1
