论文摘要
我们表明,确定性线性树换能器的等效性可以在自由组解释其输出时在多项式时间内确定。由于自由组提供的取消属性,所需的构造不仅更一般,而且比证明确定性线性树对词传感器等效的相应构造更简单。
We show that equivalence of deterministic linear tree transducers can be decided in polynomial time when their outputs are interpreted over the free group. Due to the cancellation properties offered by the free group, the required constructions are not only more general, but also simpler than the corresponding constructions for proving equivalence of deterministic linear tree-to-word transducers.
