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

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

                The problem is Match-bounded by 0.
                The enriched problem is compatible with the following automaton:

      The usable rules for this path are empty.
      
        We have oriented the usable rules with the following strongly linear interpretation:
