Problem:
 2nd(cons1(X,cons(Y,Z))) -> Y
 2nd(cons(X,X1)) -> 2nd(cons1(X,X1))
 from(X) -> cons(X,from(s(X)))

Proof:
 DP Processor:
  DPs:
   2nd#(cons(X,X1)) -> 2nd#(cons1(X,X1))
   from#(X) -> from#(s(X))
  TRS:
   2nd(cons1(X,cons(Y,Z))) -> Y
   2nd(cons(X,X1)) -> 2nd(cons1(X,X1))
   from(X) -> cons(X,from(s(X)))
  ADG Processor:
   DPs:
    2nd#(cons(X,X1)) -> 2nd#(cons1(X,X1))
    from#(X) -> from#(s(X))
   TRS:
    2nd(cons1(X,cons(Y,Z))) -> Y
    2nd(cons(X,X1)) -> 2nd(cons1(X,X1))
    from(X) -> cons(X,from(s(X)))
   graph:
    from#(X) -> from#(s(X)) -> from#(X) -> from#(s(X))
   SCC Processor:
    #sccs: 1
    #rules: 1
    #arcs: 1/4
    DPs:
     from#(X) -> from#(s(X))
    TRS:
     2nd(cons1(X,cons(Y,Z))) -> Y
     2nd(cons(X,X1)) -> 2nd(cons1(X,X1))
     from(X) -> cons(X,from(s(X)))
