.(.(x, y), z) -> .(x, .(y, z))

Innermost Termination of R to be shown.

`   R`
`     ↳Dependency Pair Analysis`

R contains the following Dependency Pairs:

.'(.(x, y), z) -> .'(x, .(y, z))
.'(.(x, y), z) -> .'(y, z)

Furthermore, R contains one SCC.

`         ↳Polynomial Ordering`

Dependency Pair:

.'(.(x, y), z) -> .'(y, z)

Rule:

.(.(x, y), z) -> .(x, .(y, z))

Strategy:

innermost

The following dependency pair can be strictly oriented:

.'(.(x, y), z) -> .'(y, z)

There are no usable rules for innermost that need to be oriented.

Used ordering: Polynomial ordering with Polynomial interpretation:
 POL(.(x1, x2)) =  1 + x2 POL(.'(x1, x2)) =  x1

resulting in one new DP problem.

Dependency Pair:

Rule:

.(.(x, y), z) -> .(x, .(y, z))

Strategy:

innermost

Using the Dependency Graph resulted in no new DP problems.
