At the same time, we try to maintain the quality and pace of our publications as you are used to. It is therefore my pleasure to present you the first issue of this year. It contains two scientific articles. The first contribution, A description language for chess , by Manuel Cristóbal López-Michelone and Jorge Ortega-Arjona, presents a straightforward representation language for chess positions as patterns. By using this chess pattern language a computer program is able to find more easily similar chess configurations. Further, this language can be used to explain why some typical maneuvers actually work in some patterns. The second contribution, games for teaching reinforcement learning , by and is using games for educational purposes. They argue that games such as highly suitable for this due to their simplicity and These can be characterized as single-player stochastic puzzle games, which consist of sliding numbered-tiles that combine to form tiles with larger numbers. The article proposes a guideline for using these games for teaching reinforcement-learning and computer-game algorithms.
