Combinatorial games modeling seki in GO

Discrete Mathematics, 2014
This paper describes results and conjectures on two closely related games, SEKI and D-SEKI, played on matrices of non-negative integers. These games were inspired of so-called seki positions in the game Go. This paper should be viewed as an investigation into the structure of SEKI and D-SEKI, without particular practical applications to Go.

Thermal Cycle–Microstructure–Property Relationships in Rail Steel Heat‐Affected Zone Simulated by Gleeble

Advanced Engineering Materials, EarlyView.
Microstructural evolution of premium rail steel during flash butt welding (FBW), comparing physically simulated heat‐affected zones with actual weld regions. Thermal cycles induce phase transformations and microstructural heterogeneity that influence weld quality and mechanical performance. These findings provide insights into optimizing FBW parameters

PSPACE-hardness of some combinatorial games

Journal of Combinatorial Theory, Series A, 1987
PSPACE-hardness of four families of win-lose-draw games played on a digraph with blocking, capture, or annihilation rules is proved. Special cases of three of the families are shown to be PSPACE-complete. Further, the PSPACE-completeness of six families of win-lose games in which two players mark or remove nodes of digraphs according to given rules is ...

Microstructural Evolution and In Situ Formation of TiB and TiC in Ti─5Al─2.5Sn Alloy Processed by Powder Metallurgy

Advanced Engineering Materials, EarlyView.
Accelerated in situ formation of TiB and TiC in Ti–5Al–2.5Sn–B4C is driven by transient liquid phase formation, which enhances particle reactions and microstructural evolution. This process increases hardness and establishes a coupled relationship between sintering temperature and reinforcement content, strongly influencing porosity in the resulting ...

Microstructural, Mechanical, and Textural Evolution of Dissimilar Combination of Laser‐Welded Maraging Steel and 4340 Steel

Advanced Engineering Materials, EarlyView.
The present work reports the microstructural, mechanical, and texture evolution of a dissimilar combination laser‐welded maraging steel with 4340 steel. This is important for aerospace applications. The demand for dissimilar welding is growing rapidly with the requirement of efficient and durable joints.

Integration of Low‐Voltage Nanoscale MoS2 Memristors on CMOS Microchips

Advanced Functional Materials, EarlyView.
This article presents the first monolithic integration of nanoscale MoS2‐based memristors into the back‐end‐of‐line of foundry‐fabricated CMOS microchips in a one‐transistor‐one‐resistor (1T1R) architecture. The MoS2‐based 1T1R cells exhibit forming‐free, nonvolatile resistive switching with ultra‐low operating voltages, low cycle‐to‐cycle variability ...

Combinatorial analysis of Tetris-like games

Discrete Mathematics, 2008
Combinatorial properties of tetris-like games are studied by using Schützenberger methodology and probability generating functions. It is proved that every tetris-like game is equivalent to a finite state automaton. A straightforward algorithm to transform a Tetris-like game into its corresponding automaton is presented.

From Nash Equilibria to Chain Recurrent Sets: An Algorithmic Solution Concept for Game Theory

Entropy, 2018
In 1950, Nash proposed a natural equilibrium solution concept for games hence called Nash equilibrium, and proved that all finite games have at least one.
