↳Argument Filtering and Ordering

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

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

f(x, f(y,z)) -> f(f(x,y),z)

The following dependency pair can be strictly oriented:

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

The following rules can be oriented:

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

f(x, f(y,z)) -> f(f(x,y),z)

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

a > b

resulting in one new DP problem.

Used Argument Filtering System:

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

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

The following remains to be proven:

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

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

f(x, f(y,z)) -> f(f(x,y),z)
