An Old School Genetic Algorithm News

Interesting finding this one! Just click on the picture above and read the news! It's from 1986 and published on Tuscaloosa News. I think it summarizes some aspects of the good times at The Clearing House for Genetic Algorithms. Very old school, indeed.

Five Years Of Genetic Argonaut

Just before lunch, I reminded this humble blog is achieving its fifth anniversary this day, March 20. A lot of nice stuffs have happened since the beginnings five years ago and I am happy that something that started just as a manner to keep me interested in evolutionary computation could achieve some nice "results", such as the history of evolution strategies post and the publication of a post of mine on the ACM newsletter SIGevolution (Grazie, Pier Luca!).

Along all these years I made some new friends on the blogosphere -- most of them I have never met in person, but I am pretty sure they exist indeed :-) -- and I profound regret any mistake I may have committed to some of them at a given moment.

Despite the blog has been operating on an irregular posting basis, there are nice posts for the coming months. Just stay tuned! :)

Thank you so much for your visits after all these years!

Evolving Wind Turbine Blades Through Simulated Evolution

Nice video this one:

Evolving Wind Turbine Blades.

Its author applied a genetic algorithm to evolve/optimize the blade shape of a wind turbine. It reminded me of Professor Ingo Rechenberg's work on a similar task: The BERWIAN (Berliner-Windkraft-Anlage) in which his group applied another kind of evolutionary algorithm -- evolution strategies.

The «Berwian» windmill by Ingo Rechenberg takes advantage of the complex eddy effect. Active paddle tips are turned towards the centre, where the turbine is placed. The windmill was optimized by the method of «evolution strategy» at many levels (number and position of the blades, profiles, etc.).

As we are talking about green/clean energy resources, don't miss the chance of reading an interesting post at Martin Pelikan's blog on the same poetical vein (solar panels).
