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

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

↳Argument Filtering and Ordering

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

innermost

The following dependency pair can be strictly oriented:

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

The following usable rule for innermost can be oriented:

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

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

a > f

resulting in one new DP problem.

Used Argument Filtering System:

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

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