Logics for Qualitative Reasoning
1st Workshop on Logics for Qualitative Modelling and Reasoning (LQMR'15), Photos
Workshop Applications of Logics in Artificial Intelligence ALAI 2013
The team consisting of three members of the Logics for Qualitative Reasoning project (Tomasz Lechowski, Przemysław Wałęga, and Michał Zawidzki) participated in ECAI 2014 Angry Birds AI Competition. Angry Birds is a video game in which the main aim is to destroy all pigs located in a given level using a slingshot and birds of various kinds. In most cases pigs are positioned among other objects - building blocks, rocks or specifically profiled ground - whose behaviour reflects the laws of physics. Participants of the Angry Birds AI Competition develop playing agents that are able to play the game on their own without any human interaction. Our team developed an agent which aims to imitate human reasoning. It uses two methods of qualitative reasoning - vertical impact and horizontal impact reasoning - in order to choose the best possible target. Both of these methods are based on several notions such as stability, being above, being to the right of, being a shelter of. The agent assigns a list of certain numerical and logical values to all the objects in the game based on the size, relative location, and material of these objects. It then proceeds with the qualitative reasoning in order to estimate the influence of one object on another. For instance, if an object A is situated on the top of object B, then the agent reasons (via vertical impact reasoning) that the destruction of object B will lead to the fall of object A. Similarly, if an object A is directly to the right of object B, then the agent reasons (via horizontal impact reasoning) that shooting at B will also affect A. The object which has the largest influence on the highest number of pigs is chosen as the target. For the detailed description of the algorithm and the reasoning methods see the paper Qualitative physics in Angry Birds: first results.
The competition was held during the 21st European Conference on Artificial Intelligence. Teams from 12 different countries from 3 continents took part in the competition. An unmodified version of the last year's winner and several other returning teams were among the participants this year. The competition was fierce and the quality of this year's agents far surpassed those of the previous competitions (last year's winner failed to qualify into the quaterfinals this year). Our agent made a promising debut. It was the best amongst those who failed to reach the semi final stage and finished 5th overall. See 2014 Competition Results.
