The following dependency pairs can be strictly oriented:

*'(c(x, y), z) -> *'(y, z)
*'(c(x, y), z) -> *'(x, z)

There are no usable rules for innermost w.r.t. to the implicit AFS that need to be oriented.

Strategy:

innermost

The following dependency pair can be strictly oriented:

*'(x, c(y, z)) -> *'(x, y)

There are no usable rules for innermost w.r.t. to the implicit AFS that need to be oriented.

Used ordering: Polynomial ordering with Polynomial interpretation:

POL(c(x₁, x₂)) = 1 + x₁

POL(*'(x₁, x₂)) = x₂

resulting in one new DP problem.
