innermost

The following dependency pair can be strictly oriented:

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

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

Used ordering: Homeomorphic Embedding Order with EMB

resulting in one new DP problem.

Used Argument Filtering System:

J(x,_{1}x) -> J(_{2}x,_{1}x)_{2}
