Editorial: Research trends

Since the 1950s, the AI community has been developing techniques in order to outperform humans for a particular game. This has been accomplished in many board games such as Chess, Checkers, and Go. Recently, new challenges have been proposed such as real-time strategy (RTS) games. Here the agents have to make decisions in real-time environments that have imperfect information, nondeterminism, and a continuous action space. It seemed that achieving super-human performance for them would take a couple of years. However, developments in Game AI are going fast. Early 2019 DeepMind announced that their agent ALPHASTAR, by using deep neural networks, has defeated two top professional players in the RTS game StarCraft II. Would this mean that we would be done in a couple of years as we are running out of games to establish superhuman performance? The answer is no, as there are still many other challenges in Game AI research. One of them is automatically developing a game or generating content (game-levels) for it. The first article of this issue deals with this research trend. In Using patterns as objectives for general video game level generation by Adeel Zafar, Hasan Mujtaba, Mirza Tauseef Baig and Mirza Omer Beg, a genetic algorithm is proposed to automatically generate levels for video games. Their generator finished at the third place in the 2018 general video-game level generation competition.
