failure 'Failure("No result of SMT solver - maybe due to some flag of the solver? or the solver was not found in PATH?")' in subprocess 869
YES

Problem:
 a__2nd(cons(X,cons(Y,Z))) -> mark(Y)
 a__from(X) -> cons(mark(X),from(s(X)))
 mark(2nd(X)) -> a__2nd(mark(X))
 mark(from(X)) -> a__from(mark(X))
 mark(cons(X1,X2)) -> cons(mark(X1),X2)
 mark(s(X)) -> s(mark(X))
 a__2nd(X) -> 2nd(X)
 a__from(X) -> from(X)

Proof:
 WPO Processor:
  algebra: Max
  weight function:
   w0 = 0
   w(2nd) = w(a__2nd) = 3
   w(from) = w(s) = w(a__from) = w(mark) = w(cons) = 0
  status function:
   st(cons) = [1, 0]
   st(2nd) = st(from) = st(s) = st(a__from) = st(mark) = st(a__2nd) = [0]
  subterm penalty function:
   sp(2nd, 0) = sp(a__2nd, 0) = 2
   sp(from, 0) = sp(a__from, 0) = 1
   sp(s, 0) = sp(mark, 0) = sp(cons, 1) = sp(cons, 0) = 0
  precedence:
   mark > a__2nd > a__from > 2nd ~ from ~ s ~ cons
