innermost

The following dependency pair can be strictly oriented:

F(a,x) -> F(g(x),x)

The following usable rule for innermost w.r.t. to the AFS can be oriented:

g(h(x)) -> g(x)

Used ordering: Lexicographic Path Order with Non-Strict Precedence with Quasi Precedence:

a > g

resulting in one new DP problem.

Used Argument Filtering System:

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

g(x) -> g_{1}

Using the Dependency Graph resulted in no new DP problems.
