Certification Problem

Input (TPDB SRS_Standard/Wenzel_16/babababaa-aaabababababa.srs)

The rewrite relation of the following TRS is considered.

b(a(b(a(b(a(b(a(a(x1))))))))) → a(a(a(b(a(b(a(b(a(b(a(b(a(x1))))))))))))) (1)

Property / Task

Prove or disprove termination.

Answer / Result

No.

Proof (by matchbox @ termCOMP 2023)

1 String Reversal

Since only unary symbols occur, one can reverse all terms and obtains the TRS
a(a(b(a(b(a(b(a(b(x1))))))))) → a(b(a(b(a(b(a(b(a(b(a(a(a(x1))))))))))))) (2)

1.1 Loop

The following loop proves nontermination.
