Misere Nim饱和的Sprague-Grundy函数

The Sprague-Grundy Functions of Saturations of Misere Nim

Yuki Irie

摘要:

我们认为尼姆的不幸是一个正常的游戏从尼姆删除终端位置。虽然尼姆和韦尔特博弈中的斯普拉格-格伦迪函数有明确的公式,但米泽尔·尼姆的函数没有明确的公式。这三场比赛都可以被认为是尼姆的位置限制。它们之间有什么区别?我们指出,尼姆和韦尔特的游戏是饱和的,但尼姆小姐不是。此外,我们提出了显式公式的Sprague-Grundy函数的饱和misère Nim,这是获得从misère Nim通过连接一些移动。

英文摘要:

We consider misère Nim as a normal-play game obtained from Nim by removing the terminal position. While explicit formulas are known for the Sprague-Grundy functions of Nim and Welter's game, no explicit formula is known for that of misère Nim. All three of these games can be considered as position restrictions of Nim. What are the differences between them? We point out that Nim and Welter's game are saturated, but misère Nim is not. Moreover, we present explicit formulas for the Sprague-Grundy functions of saturations of misère Nim, which are obtained from misère Nim by adjoining some moves.
