AI总结:

本文提出最小-最大加权自动机确定性问题的第一个复杂性界限,并通过构造性框架改进了可判定性论证。

摘要:

最小-最大加权自动机的确定性问题最近已被证明是可判定的。然而,该证明完全是存在性的,依赖于多个非构造性的论点。本文的贡献是双方面的:首先,我们提出了该问题的第一个复杂性界限,将其置于快速增长层级中。其次,我们的技术引入了一个灵活的框架,以构造性的方式分析加权自动机的运行。特别是,这大大简化了之前的可判定性论证,并提供了更精确的分析,从而成为获得精确复杂性界限的关键步骤。

英文摘要:

The determinisation problem for min-plus (tropical) weighted automata was recently shown to be decidable. However, the proof is purely existential, relying on several non-constructive arguments. Our contribution in this work is twofold: first, we present the first complexity bound for this problem, placing it in the Fast-growing hierarchy. Second, our techniques introduce a versatile framework to analyse runs of weighted automata in a constructive manner. In particular, this significantly simplifies the previous decidability argument and provides a tighter analysis, thus serving as a critical step towards a tight complexity bound.
