'Weak Dependency Graph [60.0]'
------------------------------
Answer:           YES(?,O(n^1))
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  terms(N) -> cons(recip(sqr(N)))
     , sqr(0()) -> 0()
     , sqr(s()) -> s()
     , dbl(0()) -> 0()
     , dbl(s()) -> s()
     , add(0(), X) -> X
     , add(s(), Y) -> s()
     , first(0(), X) -> nil()
     , first(s(), cons(Y)) -> cons(Y)}

Details:         
  We have computed the following set of weak (innermost) dependency pairs:
   {  terms^#(N) -> c_0(sqr^#(N))
    , sqr^#(0()) -> c_1()
    , sqr^#(s()) -> c_2()
    , dbl^#(0()) -> c_3()
    , dbl^#(s()) -> c_4()
    , add^#(0(), X) -> c_5()
    , add^#(s(), Y) -> c_6()
    , first^#(0(), X) -> c_7()
    , first^#(s(), cons(Y)) -> c_8()}
  
  The usable rules are:
   {}
  
  The estimated dependency graph contains the following edges:
   {terms^#(N) -> c_0(sqr^#(N))}
     ==> {sqr^#(s()) -> c_2()}
   {terms^#(N) -> c_0(sqr^#(N))}
     ==> {sqr^#(0()) -> c_1()}
  
  We consider the following path(s):
   1) {  terms^#(N) -> c_0(sqr^#(N))
       , sqr^#(0()) -> c_1()}
      
      The usable rules for this path are empty.
      
        We have oriented the usable rules with the following strongly linear interpretation:
          Interpretation Functions:
           terms(x1) = [0] x1 + [0]
           cons(x1) = [0] x1 + [0]
           recip(x1) = [0] x1 + [0]
           sqr(x1) = [0] x1 + [0]
           0() = [0]
           s() = [0]
           dbl(x1) = [0] x1 + [0]
           add(x1, x2) = [0] x1 + [0] x2 + [0]
           first(x1, x2) = [0] x1 + [0] x2 + [0]
           nil() = [0]
           terms^#(x1) = [0] x1 + [0]
           c_0(x1) = [0] x1 + [0]
           sqr^#(x1) = [0] x1 + [0]
           c_1() = [0]
           c_2() = [0]
           dbl^#(x1) = [0] x1 + [0]
           c_3() = [0]
           c_4() = [0]
           add^#(x1, x2) = [0] x1 + [0] x2 + [0]
           c_5() = [0]
           c_6() = [0]
           first^#(x1, x2) = [0] x1 + [0] x2 + [0]
           c_7() = [0]
           c_8() = [0]
