TRS:

  a__zeros() -> cons(0(),zeros())
  a__tail(cons(X,XS)) -> mark(XS)
  mark(zeros()) -> a__zeros()
  mark(tail(X)) -> a__tail(mark(X))
  mark(cons(X1,X2)) -> cons(mark(X1),X2)
  mark(0()) -> 0()
  a__zeros() -> zeros()
  a__tail(X) -> tail(X)

linear polynomial interpretations on N:

  a__zeros_A = 3
  a__zeros#_A = 3
  cons_A(x1,x2) = x1 + x2 + 2
  cons#_A(x1,x2) = x1 + x2 + 2
  0_A = 0
  0#_A = 0
  zeros_A = 0
  zeros#_A = 0
  a__tail_A(x1) = x1 + 3
  a__tail#_A(x1) = x1 + 3
  mark_A(x1) = x1 + 4
  mark#_A(x1) = x1 + 4
  tail_A(x1) = x1 + 3
  tail#_A(x1) = x1 + 3

precedence:

  zeros > a__zeros > 0 > mark > cons = a__tail > tail
