'Weak Dependency Graph [60.0]'
------------------------------
Answer:           YES(?,O(n^1))
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  a(a(x1)) -> b(b(b(x1)))
     , b(b(x1)) -> c(c(c(x1)))
     , c(c(x1)) -> d(d(d(x1)))
     , b(x1) -> d(d(x1))
     , c(d(d(x1))) -> a(x1)}

Details:         
  We have computed the following set of weak (innermost) dependency pairs:
   {  a^#(a(x1)) -> c_0(b^#(b(b(x1))))
    , b^#(b(x1)) -> c_1(c^#(c(c(x1))))
    , c^#(c(x1)) -> c_2()
    , b^#(x1) -> c_3()
    , c^#(d(d(x1))) -> c_4(a^#(x1))}
  
  The usable rules are:
   {  b(b(x1)) -> c(c(c(x1)))
    , c(c(x1)) -> d(d(d(x1)))
    , b(x1) -> d(d(x1))
    , c(d(d(x1))) -> a(x1)
    , a(a(x1)) -> b(b(b(x1)))}
  
  The estimated dependency graph contains the following edges:
   {a^#(a(x1)) -> c_0(b^#(b(b(x1))))}
     ==> {b^#(b(x1)) -> c_1(c^#(c(c(x1))))}
   {a^#(a(x1)) -> c_0(b^#(b(b(x1))))}
     ==> {b^#(x1) -> c_3()}
   {b^#(b(x1)) -> c_1(c^#(c(c(x1))))}
     ==> {c^#(d(d(x1))) -> c_4(a^#(x1))}
   {b^#(b(x1)) -> c_1(c^#(c(c(x1))))}
     ==> {c^#(c(x1)) -> c_2()}
   {c^#(d(d(x1))) -> c_4(a^#(x1))}
     ==> {a^#(a(x1)) -> c_0(b^#(b(b(x1))))}
  
  We consider the following path(s):
   1) {  a^#(a(x1)) -> c_0(b^#(b(b(x1))))
       , c^#(d(d(x1))) -> c_4(a^#(x1))
       , b^#(b(x1)) -> c_1(c^#(c(c(x1))))
       , c^#(c(x1)) -> c_2()}
      
      The usable rules for this path are the following:
      {  b(b(x1)) -> c(c(c(x1)))
       , c(c(x1)) -> d(d(d(x1)))
       , b(x1) -> d(d(x1))
       , c(d(d(x1))) -> a(x1)
       , a(a(x1)) -> b(b(b(x1)))}
      
        We have applied the subprocessor on the union of usable rules and weak (innermost) dependency pairs.
