Our poster was accepted in the ECTA conference and we recently presented it in Porto. Have a look at the paper and poster source https://github.com/geneura-papers/2016-ea-languages-PPSN/releases/tag/v1.0ECTA that uses Knitr, and check out the poster.
The cloud is where you run your applications, but it’s also how you will design your algorithms from now on. Evolutionary algorithms are specially suited for this, and that is why I have given tutorials on how to adapt evolutionary algorithms to the cloud in PPSN and lately, when one of the keynotes dropped, an updated and abridged version at ECTA 16.
In these tutorials I make an introduction to what is the cloud and what it means: basically, create applications as loosely connected, polyglot, multi-vendor sets of different programs. Which will spawn a slew of new algorithms, starting with the pool-based evolutionary algorithm we have working on for so long.
As we usually do, we attended GECCO 2016 this year, a genetic and evolutionary algorithm confernce which took place in Denver, in America.
The paper accepted in the Parallel Evolutionary Systems session and two papers presented in workshops dealt with pool-based evolutionary algorithms and their implementation in volunteer computer systems in browsers. Unlike mainstream evolutionary algorithms, which put the algorithm and the population in the same process or thread, pool based evolutionary algorithms decouple population from algorithms, allowing these to work ephemerally, spontaneously and in a completely asynchronous way.
How Can we Make the User more Efficient in Interactive Evolutionary Algorithms?, which was an exposition of how what the web page shows has a clear influence on the time the user spends in it and thus on the performance of the system, and also a call for help from this visualization workshop on how to make this time as long as possible. We received many helpful comments, including using badges for users (how this could be done without authentication, which would be a barrier, is not so easy to work out) or creating leaderboards so users can compete with each other.
The paper presented in GECCO proper entitled Performance for the masses
Experiments with A Web Based Architecture to Harness Volunteer Resources for Low Cost Distributed Evolutionary Computation, dealt with a series of experiments using the platform NodIO published in OpenShift. It has actually been running continuously for a year, although the number of volunteers is close to 0. I will have to check it out, anyway, this long term behavior would be interesting. The paper presented how the behavior of the user presents some patterns, including the fact that their contributions follow a Weibull distribution, very close to what happens in games. Which, in fact is what lead us to submit the first paper to the visualization workshop.
As usual, all our papers are open source and reside in GitHub. If you want copies, just leave a comment and we’ll email them to you.
As part of the EvoStar conference, which took place last week, we presented the poster Benchmarking Languages for Evolutionary Algorithms, where, with help from many friends in Open Science fashion, we tested several a bunch of compiled and scripting languages on several common evolutionary operations: crossover, mutation and OneMax.
It was presented in poster form, and you had to be there to actually understand it. Since you are not, it’s better if you use this comments (or those at the poster) to inquire about it. Or you can check out the interactive presentation we also did, which in fact includes data and everything in the source.
This work is ongoing, and you are very welcome to participate. Just take a peek at the repo, and do a pull request.
During EvoStar, our group presented several papers on games, multiobjective optimization and implementation of evolutoinary algorithms. This paper was presented as a full talk at EvoGAMES 2016 in Porto (Portugal). BY: Antonio Fernández Ares, Pablo García-Sánchez, Antonio M. Mora García, Pedro A. Castillo, Juan J. Merelo
