On Remoteness Functions of Exact Slow -NIM with Piles

V Gurvich, D Martynov, V Maximchuk… - arXiv preprint arXiv …, 2023 - arxiv.org
Given integer $ n $ and $ k $ such that $0< k\leq n $ and $ n $ piles of stones, two player
alternate turns. By one move it is allowed to choose any $ k $ piles and remove exactly one …

Computing remoteness functions of Moore, Wythoff, and Euclid's games

E Boros, V Gurvich, K Makino, M Vyalyi - International Journal of Game …, 2024 - Springer
We study remoteness function R of impartial games introduced by Smith in 1966. The player
who moves from a position x can win if and only if R (x) is odd. The odd values of R (x) show …

On the Sprague–Grundy function of extensions of proper Nim

E Boros, V Gurvich, NB Ho, K Makino - International journal of game theory, 2021 - Springer
We consider the game of proper Nim, in which two players alternately move by taking stones
from n piles. In one move a player chooses a proper subset (at least one and at most n-1 n …

Impartial games with decreasing Sprague–Grundy function and their hypergraph compound

E Boros, V Gurvich, NB Ho, K Makino… - International Journal of …, 2023 - Springer
Abstract The Sprague–Grundy (SG) theory reduces the disjunctive compound of impartial
games to the classical game of NIM. We generalize this concept by introducing hypergraph …

k≤ n, we study two impartial combinatorial games, Nim1n,≤ kand Nim1n,= k. In the first …

On Computational hardness of multidimensional subtraction games

V Gurvich, M Vyalyi - Algorithms, 2021 - mdpi.com
We study the algorithmic complexity of solving subtraction games in a fixed dimension with a
finite difference set. We prove that there exists a game in this class such that solving the …

Computational Utilities for the Game of Simplicial Nim

N Penn - 2021 - uknowledge.uky.edu
Simplicial nim games, a class of impartial games, have very interesting mathematical
properties. Winning strategies on a simplicial nim game can be determined by the set of …

E Boros, V Gurvich - INTEGERS, 2023 - math.colgate.edu
The classical game of Nim can be naturally extended and played on an arbitrary hypergraph
H⊆ 2V\{∅} whose vertices V={1,..., n} correspond to piles of stones. By one move, a player …
