Problem:
 a(b(a(a(b(x1))))) -> c(c(c(c(a(x1)))))
 c(x1) -> b(a(a(b(x1))))

Proof:
 DP Processor:
  DPs:
   a#(b(a(a(b(x1))))) -> a#(x1)
   a#(b(a(a(b(x1))))) -> c#(a(x1))
   a#(b(a(a(b(x1))))) -> c#(c(a(x1)))
   a#(b(a(a(b(x1))))) -> c#(c(c(a(x1))))
   a#(b(a(a(b(x1))))) -> c#(c(c(c(a(x1)))))
   c#(x1) -> a#(b(x1))
   c#(x1) -> a#(a(b(x1)))
  TRS:
   a(b(a(a(b(x1))))) -> c(c(c(c(a(x1)))))
   c(x1) -> b(a(a(b(x1))))
