动态化的库塞勒定理

Courcelle's Theorem Made Dynamic

Patricia Bouyer-Decitre, Vincent Jugé, Nicolas Markey

摘要:

动态复杂度是指当输入稍微改变时,更新问题的输出。我们研究了动态复杂性的模型检验一个固定的一元二阶公式在一个固定的最大图有界树宽度的子图的发展,在这里的子图的发展失去或获得边缘(从最大图)。我们表明,这个问题是在DynFO(与LOGSPACE预计算),通过减少一个戴克可达性问题的非循环自动机。

英文摘要:

Dynamic complexity is concerned with updating the output of a problem when the input is slightly changed. We study the dynamic complexity of model checking a fixed monadic second-order formula over evolving subgraphs of a fixed maximal graph having bounded tree-width; here the subgraph evolves by losing or gaining edges (from the maximal graph). We show that this problem is in DynFO (with LOGSPACE precomputation), via a reduction to a Dyck reachability problem on an acyclic automaton.
