摘要:

迫零是一种在图上进行的组合游戏,其目标是从所有未填充的顶点开始,并以最小的代价将它们填充。在游戏的原始版本中,有两个选项。也就是说,以单个令牌为代价填充任何一个顶点;或者如果任何当前填充的顶点具有唯一的未填充邻居,则免费填充邻居。本文研究了一个$q$ -模拟的迫零,引入了第三个选项,涉及一个预言。建立了该对策的基本性质,包括确定所有可能的$q$具有最小代价$1$或$2$的图,以及当$q=1$ .

英文摘要:

Zero forcing is a combinatorial game played on a graph where the goal is to start with all vertices unfilled and to change them to filled at minimal cost. In the original variation of the game there were two options. Namely, to fill any one single vertex at the cost of a single token; or if any currently filled vertex has a unique non-filled neighbor, then the neighbor is filled for free. This paper investigates a $q$-analogue of zero forcing which introduces a third option involving an oracle. Basic properties of this game are established including determining all graphs which have minimal cost $1$ or $2$ for all possible $q$, and finding the zero forcing number for all trees when $q=1$.
