Videogames have become one of the most prolific and interesting testbed for research in the last few years; mainly due to their growing impact on both, the society and in the scientific community. Thus, there are arising many tools and frameworks aimed to ease the implementation and test of effective Artificial Intelligence engines, able to control challenging or human-like autonomous agents (NPCs, Non-Player Characters). However, many of these engines are still implemented using basic techniques and just a few of them apply advanced Computational Intelligence methods. Moreover, videogames are themselves a varied domain with many other problems to address, that researchers are becoming to study. This talk will introduce videogames as a research domain and will present the main problems to solve as well as the main CI techniques applied in this scope.
