Certification Problem

Input (TPDB TRS_Standard/Transformed_CSR_04/Ex6_GM04_L)

The rewrite relation of the following TRS is considered.

c f (1)
f g (2)

Property / Task

Prove or disprove termination.

Answer / Result

Yes.

Proof (by ttt2 @ termCOMP 2023)

1 Rule Removal

Using the Weighted Path Order with the following precedence and status
prec(g) = 0 status(g) = [] list-extension(g) = Lex
prec(f) = 0 status(f) = [] list-extension(f) = Lex
prec(c) = 1 status(c) = [] list-extension(c) = Lex
and the following Max-polynomial interpretation
[g] = max(2)
[f] = max(4)
[c] = max(4)
all of the following rules can be deleted.
c f (1)
f g (2)

1.1 R is empty

There are no rules in the TRS. Hence, it is terminating.
