If the question answering step's complexity could be reduced to $O(|S|)$, MSO query answering on structures of bounded treewidth -would then be known to be in \lineardelaylin. Or is there a lower bound on +would then be known to be solvable in +\qptime{$O_{\varphi}(n)$}{$O_{\varphi}(m)$}. Or is there a lower bound on computing LCA closures in this setting, for example, would it be possible to reduce comparison sorting to computing LCA closures? |
