Computational hardness of multidimensional subtraction games
P. 237–249.
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 game is (formula presented)-complete and requires time (formula presented), where n is the input size. This bound is optimal up to a polynomial speed-up. The results are based on the construction introduced by Larsson and Wästlund. It relates subtraction games and cellular automata. © Springer Nature Switzerland AG 2020.

Array DBMSs operate on big N-d arrays. Cellular automata (CA) work on a discrete lattice of cells, essentially on N-d arrays. CA facilitate decision support as they realistically simulate complex phenomena including road traffic, fire spread, and urban growth. Array DBMSs can bring numerous benefits to the CA domain via a ``database approach'': powerful parallelization, ...

Array DBMSs manage big N-d arrays, are not yet widely known, but are experiencing an R&D surge due to the rapid growth of array volumes. Cellular automata (CA) operate on a discrete lattice of cells that can be modeled by an N-d array. CA are successfully applied to model fire spread, land cover change, road ...

This article is devoted to the application of the cellular automata mathematical apparatus to the problem of continuous optimization. The cellular automaton with an objective function is introduced as a new modification of the classic cellular automaton. The algorithm of continuous optimization, which is based on dynamics of the cellular automaton having the property of ...

Настоящая работа посвящена построению и первичному исследованию варианта модели «власть-общество» на основе стохастического клеточного автомата, описывающего динамику распределения власти в иерархии. Сформулированы лежащие в основе модели положения, проведена алгоритмизация и построена имитационная система, позволяющая проводить вычислительные эксперименты с моделью. Показано, что большая часть свойств детерминированной модели, имеющей вид системы дифференциальных уравнений, сохраняется в клеточно-автоматном варианте. ...

The paper presents problems, which are connected with satellite monitoring of snowmelt process in the Perm region. It is represented research data of 2011, according to which almost every day only a small part of the observed territory can be identified due to the effect of clouds. It is proposed the algorithm, based on cellular ...

In this paper we consider construction and primary research of the stochastic cellular automaton based version of the "power-society" model, describing the dynamics of power distribution in a hierarchy. We herein formulate basic principles of the model and present a simulation system for numeric experiments. It is shown that most properties of the deterministic model ...

In this paper we deal with mathematical modeling of team sport games based on cellular automata (CA). We describe some developments of CA models of football. Presumable learning and optimization problems in team modeling based on CA are discussed. Some general problems are discussed which are related to the accounting of mentality of game participants. ...
