图上的翻转难题

The flipping puzzle on a graph

Hau-wen Huang, Chih-wen Weng

摘要:

设$S$是一个连通图,它包含$n-1$顶点的导出路,其中$n$是$S.$的阶.这个谜题的一个结构就是一个在$\{0, 1\}$上的$n$维列向量,向量的坐标由顶点集$S$索引.对于具有坐标$u_s=1$的每个配置$u$,存在将$u$发送到新配置的移动,该移动翻转$u.$中与$s$相邻的坐标的条目。我们完全确定一个配置是否可以在有限步骤的序列中移动到另一个配置。

英文摘要:

Let $S$ be a connected graph which contains an induced path of $n-1$ vertices, where $n$ is the order of $S.$ We consider a puzzle on $S$. A configuration of the puzzle is simply an $n$-dimensional column vector over $\{0, 1\}$ with coordinates of the vector indexed by the vertex set $S$. For each configuration $u$ with a coordinate $u_s=1$, there exists a move that sends $u$ to the new configuration which flips the entries of the coordinates adjacent to $s$ in $u.$ We completely determine if one configuration can move to another in a sequence of finite steps.
