Bio-inspired Algorithms for the Vehicle Routing Problem

And it seems our book is almost out! Springer already put it on its website and it’s announced in and UK. This book is part of the Studies in Computational Intelligence series and has some of the most recent advances of evolutionary approaches to VRP variants. I can hardly wait to see it on paper! :-)


I’ve decided to take a more serious look at CiteULike as a way to keep a list of my publications and, most important, to start a reference library. Why? Well, first it’s easy to keep your publications and have some additional services attached: tags, comments, easy export, links, etc. Second, having a livrary of articles that we like, want to read, etc, is useful in the sense that you can keep a record of your research literature. Moreover, if you start a group within your research group and/or collaborators, it might be a useful tool. And then, since it’s a social network site you could find interesting references that you probably wouldn’t see them (or maybe not). For now, I just added some of my own publications but I intend to explore and use more this site.

Paper accepted at HIS 2008

And the second paper related to the work done in INRIA is accepetd, at the 8th International Conference on Hybrid Intelligent Systems. The event will take place in Barcelona, Spain, from September 10th until the 12th. From their website: 

“The objectives of HIS 2008 are: to increase the awareness of the research community of the broad spectrum of hybrid techniques, to bring together AI researchers from around the world to present their cutting-edge results, to discuss the current trends in HIS research, to develop a collective vision of future opportunities, to establish international collaborative opportunities, and as a result to advance the state of the art of the field.

The “Tyranny of the Power Law” essay

Just came across the following blog post/essay which I found very nice to read:

Tyranny of the Power Law (and Why We Should Become Eclectic)

“(…) However, as a normative or prescriptive approach to how things shouldwork, I believe that the gaining popularity of the power law holds some dangers as well as benefits. After all, should we find it acceptable — even if it is an accurate description of how things really are — that the top 20% of people control 80% of the wealth in a society? Is it really a good idea that a few ‘hits’ (often ginned up to be that way rather than by popular demand) swamp out more meritorious ‘misses’? Is it really ultimately beneficial, efficient, or rational for a society to have a few people at the top of the power law — at least those who got there by inherited privilege and/or genetic accident — hold sway over the lives of the many who live down along the ‘long tail’ of the power law? (…)”


This post raises some interesting questions and valid points. However, we should not forget they can be useful tools. And well, I think some more work relating Power Law and EC can/should be done! ;-) 

Paper Accepted at PPSN 2008

I got accepted my first paper related to the work done in INRIA, at the 10th International Conference on 

Parallel Problem Solving From Nature. The event will take place in Dortmund, Germany, from September 13th until the 17th. The interesting fact about PPSN is the conference format. From the website:

“all accepted papers will be presented during small poster sessions of about 16 papers. Each session will contain papers from a wide variety of topics, and will begin by a plenary quick overview of all papers in that session by a major researcher in the field. Past experiences have shown that such presentation format led to more interactions between participants and to a deeper understanding of the papers.”

I agree that this might motivate the interaction between participants and thus, everyone will benefit much more from the event. I’m curious and I wish it will be a nice event since I’ve never been to PPSN before.


Talks at NCRA

The 2nd Natural Computing Research and Applications Group workshop was a success and very interesting. I got the chance to see first hand the work developed at NCRA and I liked it. I found the work of Erik Hemberg on Meta-Grammars & Grammatical Evolution interesting, as well as Sébastien Piccand’s presentation on Optimisation of PSO topology. On a side note, the slides of my talk can be found in slideshare.
