游击队减法游戏

Partizan Subtraction Games

Eric Duchêne, Marc Heinrich, Richard J. Nowakowski, Aline Parreau

摘要:

游击队减法游戏是组合游戏,其中两个玩家,比如左和右,交替地从一堆代币中移除n个代币,其中$n \in S_L$(分别为($n \in S_R$)当它是左的(分别)。右的)转动。第一个不能移动的玩家输了。这些博弈是由Fraenkel和Kotzig在1987年引入的,他们引入了优势的概念,即如果堆足够大,左总是赢的结果序列的渐近行为。在本文中,我们研究了结果序列的其他类型的行为。除了支配之外,还定义了其他三种不相交的行为,即弱支配、公平和最终公正。我们考虑的问题,计算这种行为相对于$S_L$和$S_R$,这是连接到著名的弗罗贝纽斯硬币问题。一般结果,连同算术和几何特征时,集$S_L$和$S_R$的大小最多为2。

英文摘要:

Partizan subtraction games are combinatorial games where two players, say Left and Right, alternately remove a number n of tokens from a heap of tokens, with $n \in S_L$ (resp. $n \in S_R$) when it is Left's (resp. Right's) turn. The first player unable to move loses. These games were introduced by Fraenkel and Kotzig in 1987, where they introduced the notion of dominance, i.e. an asymptotic behavior of the outcome sequence where Left always wins if the heap is sufficiently large. In the current paper, we investigate the other kinds of behaviors for the outcome sequence. In addition to dominance, three other disjoint behaviors are defined, namely weak dominance, fairness and ultimate impartiality. We consider the problem of computing this behavior with respect to $S_L$ and $S_R$, which is connected to the well-known Frobenius coin problem. General results are given, together with arithmetic and geometric characterizations when the sets $S_L$ and $S_R$ have size at most 2.
