Input (TPDB TRS_Standard/AProVE_04/forward_instantiation2)

The rewrite relation of the following TRS is considered.

f(x,y,z) g(x,y,z) (1)
g(0,1,x) f(x,x,x) (2)
a b (3)
a c (4)

Property / Task

Prove or disprove termination.

Answer / Result

Yes.

Proof (by AProVE @ termCOMP 2023)

1 Dependency Pair Transformation

The following set of initial dependency pairs has been identified.
f#(x,y,z) g#(x,y,z) (5)
g#(0,1,x) f#(x,x,x) (6)

1.1 Forward Instantiation Processor

We instantiate the pair to the following set of pairs
f#(0,1,x2) g#(0,1,x2) (7)

1.1.1 Dependency Graph Processor

The dependency pairs are split into 0 components.
