  + Considered Problem:
      - Strict TRS:
          2ndsneg(0(),Z) -> rnil()
          2ndsneg(s(N),cons(X,n__cons(Y,Z))) -> rcons(negrecip(activate(Y)),2ndspos(N,activate(Z)))
          2ndspos(0(),Z) -> rnil()
          2ndspos(s(N),cons(X,n__cons(Y,Z))) -> rcons(posrecip(activate(Y)),2ndsneg(N,activate(Z)))
          activate(X) -> X
          activate(n__cons(X1,X2)) -> cons(X1,X2)
          activate(n__from(X)) -> from(X)
          cons(X1,X2) -> n__cons(X1,X2)
          from(X) -> cons(X,n__from(s(X)))
          from(X) -> n__from(X)
          pi(X) -> 2ndspos(X,from(0()))
          plus(0(),Y) -> Y
          plus(s(X),Y) -> s(plus(X,Y))
          square(X) -> times(X,X)
          times(0(),Y) -> 0()
          times(s(X),Y) -> plus(Y,times(X,Y))
      - Signature:
          {2ndsneg/2,2ndspos/2,activate/1,cons/2,from/1,pi/1,plus/2,square/1,times/2} / {0/0,n__cons/2,n__from/1
          ,negrecip/1,posrecip/1,rcons/2,rnil/0,s/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {2ndsneg,2ndspos,activate,cons,from,pi,plus,square
          ,times} and constructors {0,n__cons,n__from,negrecip,posrecip,rcons,rnil,s}
