innermost

The following dependency pairs can be strictly oriented:

F(g(x,y),z) -> F(y,z)

F(g(x,y),z) -> F(x,z)

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(g(x)_{1}, x_{2})= 1 + x _{1}+ x_{2}_{ }^{ }_{ }^{ }POL(F(x)_{1}, x_{2})= x _{1}_{ }^{ }_{ }^{ }POL(f(x)_{1}, x_{2})= x _{2}_{ }^{ }

resulting in one new DP problem.
