Angry Birds meet EAs at EVO* 2019

Last 24 of April we presented the work “Free Form Evolution for Angry Birds Level Generation” at EVOApplications 2019 (EvoGAMES) a conference part of EVO* 2019, held in Leipzig (Germany).

The abstract of the work is:

This paper presents an original approach for building structures that are stable under gravity for the physics-based puzzle game Angry Birds, with the ultimate objective of creating fun and aesthetically pleasing Angry Birds levels with the minimum number of constraints. This approach consists of a search-based procedural level generation method that uses evolutionary algorithms. In order to evaluate the stability of the levels, they are executed in an adaptation of an open source version of the game called Science Birds. In the same way, an open source evolutionary computation framework has been implemented to fit the requirements of the problem. The main challenge has been to design a fitness function that, first, avoids if possible the actual execution of the simulator, which is time consuming, and, then, to take into account the different ways in which a structure is not structurally sound and consider them in different ways to provide a smooth landscape that eventually achieves that soundness. Different representations and operators have been considered and studied. In order to test the method four experiments have been carried out, obtaining a variety of stable structures, which is the first path for the generation of levels that are aesthetically pleasing as well as playable.

@amorag did a short presentation and later ‘defended’ a poster during the reception act. The presentation is a description of the poster:

Actually the poster was selected as the second best of the conference by the attendants. :D

Mathematics applied to the maintenance of radio communication devices

Yesterday, Alexander Lyubchenko, post-doctoral researcher from Omsk State Transport University, made a report on the topic “Mathematical support for preventive maintenance periodicity optimization of radio communication facilities”.

The presentation was:

He presented the results of his research field and shared with us ideas for future work.

A small discussion took place concerning the application of another research approaches for solving the presented task, which could provide better efficiency and accuracy of calculations… Somebody said Evolutionary Algorithms? Yes, of course! :D

Thus, it is possible to conclude that the organised event was productive.

Alexander is doing a short visit to our group until next June.
