Games, Art and Beyond at Evo*

Filed under: Congress, Real-world applications, Videogames — Tags: , , — fcofdez @ 8:01 am

Not only technology is required for living in balance. This year, besides presenting latest results on Automation Software Testing at Evo* Conference, we have also presented some kind of art for videogames.

New results on Automatic Genetic Terrain Generation were presented at EvoGames 2010, as well as this video on Chapas, the videogame using the technology developed.

Let us know of you want to become beta-tester for Chapas.

UnrealBots in EVO* 2010 (EVOGames)

Hi,

Here you are the AMAZING (:D) poster presented at EVO* 2010, inside the Workshop EVOGames.

The work describes the analysis, design and implementation of two evolutionary algorithms (a Genetic Algorithm  and a Genetic Programming one) to improve the default Artificial Intelligence of the Bots (authonomous enemies) inside the PC Game Unreal.

It had plenty of visits and millards of interest people ask me about the topics in it…

… well, to be honest just, 10 people ask me (3 of them are friends of mine), but in some moments, around 8 or 10 people were looking at the poster and making jokes with me, since it seems to be a perfect mixture between a fabulous research study (:D) and a funny PC game. ;)

Enjoy it. :D

NoHNES at Evostar Istanbul

Filed under: Congress — Tags: , , , — jjmerelo @ 6:37 pm

A substantial portion of the NoHNES teem will be in Istanbul attending the EvoStar 2010 conference. Paco Fernández, Daniel Lombraña, Anna Esparcia, Antonio Mora and myself will be there presenting two papers and one poster. My own presentation on an evolutionary MasterMind is already online, and the rest will be here shortly.
So, NoHNES will be at Evostar for the third time in a row (I talked about the first one in my other blog)

Project presentation at the IT Projects Day

Filed under: Congress, Event, Papers — Tags: , , , — jjmerelo @ 7:05 pm

Tomorrow lots of people in suits will be heading to Boadilla del Monte, in Madrid, to present their projects in a seminar in which project principal investigators will be talking about them. I am still thinking about the suit, but will be there to present this summary of our groups’ work. It’s been two quite productive years (and a half), but we have only twenty minutes to present them using this slide deck

Feel free to ask about or request any paper you see mentioned there. Most refer to ongoing research, anyways.

Presentation of our work on modeling pheromone dispensers at GECCO workshop on Symbolic Regression and Modeling

Our paper “Multiobjective Genetic Programming Approach for a Smooth Modeling of the Release Kinetics of a Pheromone Dispenser” was presented at the workshop on Symbolic Regression and Modeling, part of the Genetic and Evolutionary Computation Conference, GECCO, held in Montreal, Canada, from July 8th ot 12th, 2009.

Here’s the abstract:
The accurate modeling of the release kinetics of pheromone dispensers is a matter or great importance for ensuring that the dispenser field-life covers the right period of the pest and for optimizing the layout of dispensers in the treated area.
A new experimental dispenser has been recently designed by researchers at the Instituto Agroforestal del Mediterraneo – Centro de Ecologia Quimica Agricola (CEQA) of the Universidad Politecnica de Valencia (Spain). The most challenging problem for the modeling of the release kinetics of this dispensers is the dificulty in obtaining experimental measurements for building the model. The procedure for obtaining these data is very costly, both time and money wise, therefore the available data across the whole season are scarce. In prior work we demonstrated the utility of using Genetic Programming (GP) for this particular problem. However, the models evolved by the GP algorithm tend to have discontinuities in those time ranges where there are not available measurements. In this work we propose the use of a multiobjective Genetic Programming for modeling the performance of the CEQA dispenser. We take two approaches, involving two and nine objectives respectively. In the first one, one of the objectives of the GP algorithm deals with how well the model fits the experimental data, while the second objective measures how “smooth” the model behaviour is. In the second approach we have as many objectives as data points and the aim is to predict each point separately using the remaining ones. The results obtained endorse the utility of this approach for those modeling problems characterized by the lack of experimental data.

Presentation of the multikulti algorithm at CEC09

The Congress of Evolutionary Computation is one of the bigger and more prestigious conferences on, you guessed it, EC. Here are the slides for the talk Lourdes Araújo and myself will be presenting tomorrow.

The paper is available under request, but I guess it will be available shortly from IEEExplore. Here’s the abstract

Migration policies in distributed evolutionary algorithms are bound to have, as much as any other evolutionary operator, an impact on the overall performance. However, they have not been an active area of research until recently, and this research has concentrated on the migration rate. In this paper we compare different migration policies, including our proposed ‘multikulti’ methods, which choose the individuals that are going to be sent to other nodes based on the principle of ‘multiculturalism’: the individual sent should be as different as possible to the receiving population (represented in several possible ways). We have checked this policy on two discrete optimization problems for different number of nodes, and found that, in average or in median, multikulti policies outperform others like sending the best or a random individual; however, their advantage changes with the number of nodes involved and the difficulty of the problem. The success of this kind of policies will be explained via the measurement of entropies, which are known to have an impact in the performance of the evolutionary algorithm.

NoHNES presence at EvoStar 2009 in Tübingen

Filed under: Congress — annaesparcia @ 10:33 am

NoHNES members Anna Esparcia and Ken Sharman attended EvoStar 2009, the premier European event on Evolutionary Computation. Anna served as co-chair of EvoNUM (the 2nd European Workshop on Bio-inspired algorithms for continuous parameter optimisation) and EvoGAMES (the 1st European Workshop on Bio-inspired Algorithms in Games).

See some pictures here.

News:

  • The tandem Ekart-Esparcia, so sucessful as chairs of EvoNUM, was also voted to chair EuroGP 2010, with Sara Silva as Publications Chair.
  • The 2010 edition of EvoStar will be held in Istanbul, Turkey, on April 7th to the 9th, with Sima Uyar as Local chair .
  • The EvoWorkshops will from now on be known as EvoApplications: The European Conference of Applications of Evolutionary Computing

Our work on modeling pheromone dispensers at EvoNUM 2009

Our work on modeling pheromone dispensers for sexual confusion in agricluture was presented by Anna Esparcia in the 2nd European workshop on Bio-inspired algorithms for continuous parameter optimisation, EvoNUM 2009, which is part of EvoStar 2009, the premier European event on Evolutionary Computation.

Although the presentation was scheduled at the ungodly hour of 10:30, the comments were higly favourable. As in the previous occasion where we have presented this work, the application was received with great interest, partly because computer scientists are in general unaware of where their food comes from.
However, unlike in MAEB 2009, this time we did not get what has become a memorable comment: “Us people from Madrid only go to the country to check that cows are in fact not purple”.
