Higher Nimbers in pawn endgames on large chessboards

نویسنده

  • Noam D. Elkies
چکیده

We answer a question posed in [Elkies 1996] by constructing a class of pawn endgames onm×n boards that show the Nimbers ∗k for many large k. We do this by modifying and generalizing T.R. Dawson’s “pawns game” [Berlekamp et al. 1982]. Our construction works for m ≥ 9 and n sufficiently large; on the basis of computational evidence we conjecture, but cannot yet prove, that the construction yields ∗k for all integers k.

Blockage Detection in Pawn Endgames

In this article 4 we introduce a blockage-detection method, which manages to detect a large set of blockage positions in pawn endgames, with practically no additional overhead. By examining different elements of the pawn structure, the method checks whether the Pawns form a blockage which prevents the King from penetrating into the opponent’s camp. It then checks several criteria to find out wh...

Plays, Values, Analysis and The Complexity of Chinese Chess

Chinese Chess (Xiangqi) and Backgammon evolved from an ancient Chinese game called Liubo that was invented some 3,500 years ago [10, pp. 3–11]. Like Liubo, Xiangqi consists of one king, five pawns, and several higher order pieces, and the game is decided by capturing the opponent’s king. Unlike in Liubo, the moves of Xiangqi are not determined by the roll of dice. The dice part of the game even...

UMRAO: A Chess Endgame Tutor

Most research in computer chess has focussed on creating an excellent chess player, with relatively little concern given to modelling how humans play chess. The research reported in this paper is aimed at investigating knowledge-based chess in the context of building a prototype chess tutor, UMRAO, which helps students learn how to play bishop-pawn endgames. In tutoring it is essential to take ...

Nimbers are inevitable

This article concerns the resolution of impartial combinatorial games, and in particular games that can be split in sums of independent positions. We prove that in order to compute the outcome of a sum of independent positions, it is always more efficient to compute separately the nimbers of each independent position than to develop directly the game tree of the sum. The concept of nimber is th...

Genetic Analyses of Heat-Sensitve Pawn Mutants of PARAMECIUM AURELIA.

Heat-sensitive Pawn (ts Pawns) of Paramecium aurelia behaved normally when grown at 23 degrees but failed to avoid strong stimuli at 35 degrees . Four of the five ts Pawn lines tested were found to be allelic at a locus known also to carry temperature-independent Pawn mutations. The fifth ts Pawn line complemented all the conditional and unconditional Pawn mutants of the two known loci. This re...
