After our poster in EvoStar, GECCO 2019 saw another poster on evolution of Angry Birds structures, in this ocassion focused on the inclusion of the Box2D Physics simulation engine into the evolutionary algorithm to save using Science Birds, which improved evaluation of the structures that needed it by 100x.
The poster is minimalistic, with the intention of making it awesome.

Last April in Leipzig we presented our paper on concurrent evolutionary algorithms using Perl 6, the new, multiparadigm, language that includes Channel-based parallelism.
Perl 6 was proved to be a great testbed for concurrent evolutionary algorithms, using bioinspiration to design the algorithm. Still a lot to be done in that area, though.
JJ nos expone el trabajo “A Neural Network System for Transformation of Regional Cuisine Style” en nuestra reunión semanal.
Hoy impartimos la charla “Minería de datos metabolómicos aplicada a procesos oncológicos: estado del arte, casos de uso y herramientas.”
La II Reunión Internacional de Metabolómica y Cáncer está teniendo lugar en GRanada, concretamente en el hotel ABBA.
Most algorithms keep some kind of state: global variable that holds the optimum, a counter of the number of evaluations, some context every piece algorithm must be aware of. However, this might not be the best when we want to create cloud-native algorithms, and it’s not in the case of cloudy evolutionary algorithms. There was a bit of that in GECCO, but as long as I was attending the Perl Conference in Glasgow, and I was using Perl, I kind of switched focus from the evolutionary part (but there was a bit of that too) to the language-design part and talked about evolutionary algorithms in Perl 6. The presentation is linked from the talk description.
Main problem is that you have to create dataflows that allow the algorithm to progress, as well as work efficiently in that kind of concurrent architecture, which is similar to the serverless architecture that is our eventual target.
We’ll be continuing this research in the workshop on engineering applications in Medellín, where my keynote will deal with this same topic.
Besides the two papers we presented in GECCO workshops, our research group also had a couple of posters in the main track. Posters get a two-page publication that you can find if you want, but probably the posters themselves will be much more informative.
The first one, with Mario García, presented a new (almost) serverless architecture for evolutionary algorithms:
The second paper, with Juanlu García, Carlos Fernandes, present a structured population approach to avoid premature convergence problems with Particle Swarm Optimization algorithms
This last work shows that using a regular population structure is better for low degree of connectivity, but this degree is quite important and has a big influence on the results.
