Shogi and chess are similar games. The aim in both games is to mate the opponent's king. However, the main di erence between shogi and chess is that in shogi pieces taken from the opponent can be used again. This has important consequences for the evaluation function. In chess the material balance is vital for the evaluation of a position while in shogi the evaluation of a position is much more...

With 6-man Chess essentially solved, the available 6-man Endgame Tables (EGTs) have been scanned for zugzwang positions where, unusually, having the move is a disadvantage. Review statistics together with some highlights and positions are provided here: the complete information is available on the ICGA website. An outcome of the review is the observation that the definition of zugzwang should b...

The goals of tobacco control endgame strategies are specified in terms of the desired levels of tobacco use and/or tobacco related health consequences. Yet the strategies being considered may have other consequences beyond tobacco use prevalence, forms and related harms. Most of the proposed strategies threaten to create large black markets with potential attendant harms: corruption, high illeg...

This article presents the results of an empirical experiment designed to gain insight into what is the effect of the minimax algorithm on the evaluation function. The experiment’s simulations were performed upon the KRK chess endgame. Our results show that dependencies between evaluations of sibling nodes in a game tree and an abundance of possibilities to commit blunders present in the KRK end...

Classifying the endgame positions in Chess can be challenging for humans and is known to be a difficult task in machine learning. An evolutionary algorithm would seem to be the ideal choice. We describe our implementation of a parallel island model and evaluate it in the context of the Chess Endgame data set from the UCI machine learning repository. We are mainly interested in impact of paralle...

We propose a novel experimental method that disentangles strategicallyand non-strategicallymotivated behavior. We apply it to an indefinitely-repeated prisoner’s dilemma game to observe simultaneously how the same individual behaves in situations with future interaction and in situations with no future interaction, while controlling for expectations. This method allows us to determine the exten...

We give very simple algorithms for best play in the simplest kind of Dots and Boxes endgames: those that consist entirely loops long chains. In every such endgame we compute margin victory, assuming both players maximize numbers boxes they capture, specify a move leads to result. improve on results by Buzzard Ciere same problem: our examine only current position do not need consider game tree a...
