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

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

↳Argument Filtering and Ordering

**F(a, f( x, a)) -> F(f(a, a), x)**

f(a, f(x, a)) -> f(a, f(a, f(f(a, a),x)))

The following dependency pair can be strictly oriented:

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

The following usable rule using the Ce-refinement can be oriented:

f(a, f(x, a)) -> f(a, f(a, f(f(a, a),x)))

Used ordering: Polynomial ordering with Polynomial interpretation:

_{ }^{ }POL(a)= 1 _{ }^{ }_{ }^{ }POL(f)= 0 _{ }^{ }

resulting in one new DP problem.

Used Argument Filtering System:

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

f(x,_{1}x) -> f_{2}
