We show that any one-counter automaton with n states, if its language is non-empty, accepts some word of length at most \(O(n^2)\). This closes the gap between the previously known upper bound of \(O(n^3)\) and lower bound of \(\mathrm {\Omega }(n^2)\). More generally, we prove a tight upper bound on the length of shortest paths between arbitrary configurations in one-counter transition systems (weaker bounds have previously appeared in the literature).
