A CHESS COMPOSER OF TWO-MOVE MATE PROBLEMS

Authors: Fainshtein, Fridel | HaCohen-Kerner, Yaakov

Article Type: Research Article

Abstract: Computerized chess composers of mate problems are rare. Moreover, so far they do not produce either impressive or creative new mate problems. In this paper, we describe a model called CHESS COMPOSER . This model uses a 64-bit representation, an ordered version of Iterative-Deepening Depth-First Search, and a quality function built with the help of two international masters in chess-problem composition. The result is applied on 100 known problems. It shows that the quality of 97 problems has been improved. Some of the improvements are rather impressive considering that all of the tested problems were composed by experienced composers. …The new improved problems can be regarded as creative from the viewpoint of experts in chess compositions, because (1) they seem to be better, and (2) they are not too similar to the original problems.

POOL PHYSICS SIMULATION BY EVENT PREDICTION 2: COLLISIONS

Authors: Leckie, Will | Greenspan, Michael

Article Type: Research Article

Abstract: A predictive event-based method to simulate the physics of the game of pool is described, including event time prediction for collisions between balls and between balls and the rails and pockets of the table. The method uses the vector parametrisation of the equation of motion of a moving ball to predict analytically the time of occurrence of collision events. The method is both accurate, since it returns exact analytical solutions for ball trajectories using no linear approximations, and efficient, since it requires a minimal number of floating point operations for trajectory solution and collision prediction. It is suitable for use …within a game-tree search, which requires a great many potential shots to be modelled efficiently, and within a robotic pool system, which requires high accuracy in predicting-shot outcomes.
