我们证明,任何具有 n 个状态的单计数器自动机,如果其语言非空,则最多接受一些长度为 \(O(n^2)\) 的单词。这缩小了先前已知的 \(O(n^3)\) 上限和 \(\mathrm {\Omega}(n^2)\) 下限之间的差距。更一般地说,我们证明了单计数器转换系统中任意配置之间的最短路径长度的严格上限(较弱的界限之前已出现在文献中)。
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).
