Problem:
 h(f(f(f(h(c(),h(b(),c()))))),h(f(f(b())),b())) -> f(h(b(),f(a())))
 f(c()) -> b()

Proof:
 Uncurry Processor:
  f5(f5(h(),f5(f(),f5(f(),f5(f(),f5(f5(h(),c()),f5(f5(h(),b()),c())))))),
     f5(f5(h(),f5(f(),f5(f(),b()))),b()))
  -> f5(f(),f5(f5(h(),b()),f5(f(),a())))
  f5(f(),c()) -> b()
  Ground Confluence Processor:
   confluent by decision procedure.
