j(g(x), g(y)) -> g(j(x,y))

The following dependency pair can be strictly oriented:

J(g(x), g(y)) -> J(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})= 1 + x _{1}_{ }^{ }_{ }^{ }POL(J(x)_{1}, x_{2})= x _{1}_{ }^{ }

resulting in one new DP problem.
