论文摘要
我们显示,可以使用$ o(\ log n)$位上的确定性图灵机在$ n $ vertex树上求解列表着色。给定一个$ n $ -vertex图$ g =(v,e)$和列表$ l(v)\ subseteq \ {1,\ dots,\ dots,n \} $ in V $中的每种$ v \ in V $中的可用颜色,$ g $ for $ g $的列表着色是适当的颜色$ c $ c $ c $ c $ c $ c $ c(v)in(v)in(v)$ $ v $。
We show that List Colouring can be solved on $n$-vertex trees by a deterministic Turing machine using $O(\log n)$ bits on the worktape. Given an $n$-vertex graph $G=(V,E)$ and a list $L(v)\subseteq\{1,\dots,n\}$ of available colours for each $v\in V$, a list colouring for $G$ is a proper colouring $c$ such that $c(v)\in L(v)$ for all $v$.
