MAYBE

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

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