The following dependency pair can be strictly oriented:

G(e(x), e(y)) -> G(x,y)

There are no usable rules using the Ce-refinement that need to be oriented.

Used ordering: Polynomial ordering with Polynomial interpretation:

_{ }^{ }POL(G(x)_{1}, x_{2})= x _{1}_{ }^{ }_{ }^{ }POL(e(x)_{1})= 1 + x _{1}_{ }^{ }

resulting in one new DP problem.
