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

Proof:
 DP Processor:
  DPs:
   f#(f(a(),f(x,a())),a()) -> f#(f(x,a()),a())
   f#(f(a(),f(x,a())),a()) -> f#(a(),f(f(x,a()),a()))
  TRS:
   f(f(a(),f(x,a())),a()) -> f(a(),f(f(x,a()),a()))
  CDG Processor:
   DPs:
    f#(f(a(),f(x,a())),a()) -> f#(f(x,a()),a())
    f#(f(a(),f(x,a())),a()) -> f#(a(),f(f(x,a()),a()))
   TRS:
    f(f(a(),f(x,a())),a()) -> f(a(),f(f(x,a()),a()))

   Restore Modifier:
