Our TORCS driving controller presented at EvoGAMES 2017

Last week, @jjmerelo presented at EvoGAMES 2017 (inside Evo* 2017) our work titled “Driving in TORCS using modular fuzzy controllers”.

This paper presents a novel car racing controller for TORCS (The Open Racing Car Simulator), which is based in the combination of two fuzzy subcontrollers, one for setting the speed, and one to control the steer angle. The obtained results are quite promissing, as the controller is quite competitive even against very tough TORCS teams.

The abstract of the paper is:

When driving a car it is essential to take into account all possible factors; even more so when, like in the TORCS simulated race game, the objective is not only to avoid collisions, but also to win the race within a limited budget. In this paper, we present the design of an autonomous driver for racing car in a simulated race. Unlike previous controllers, that only used fuzzy logic approaches for either acceleration or steering, the proposed driver uses simultaneously two fuzzy controllers for steering and computing the target speed of the car at every moment of the race. They use the track border sensors as inputs and besides, for enhanced safety, it has also taken into account the relative position of the other competitors. The proposed fuzzy driver is evaluated in practise and timed races giving good results across a wide variety of racing tracks, mainly those that have many turning points.

There was an interactive presentation at the conference, together with a poster:

Mathematics applied to the maintenance of radio communication devices

Yesterday, Alexander Lyubchenko, post-doctoral researcher from Omsk State Transport University, made a report on the topic “Mathematical support for preventive maintenance periodicity optimization of radio communication facilities”.

The presentation was:

He presented the results of his research field and shared with us ideas for future work.

A small discussion took place concerning the application of another research approaches for solving the presented task, which could provide better efficiency and accuracy of calculations… Somebody said Evolutionary Algorithms? Yes, of course! :D

Thus, it is possible to conclude that the organised event was productive.

Alexander is doing a short visit to our group until next June.

Aplicando algoritmos genéticos a un controlador ‘fuzzy’ para una gestión adaptativa del tráfico

Recientemente se ha aceptado el artículo “A hybrid Fuzzy Genetic Algorithm for an adaptive traffic signal system” en la revista open-access Advances in Fuzzy Systems. En él participamos varios de los investigadores de GeNeura.

El abstract es:

This paper presents a hybrid algorithm that combines Fuzzy Logic Controller (FLC) and Genetic Algorithms (GAs) and its application on a traffic signal system. FLCs have been widely used in many applications in diverse areas, such as control system, pattern recognition, signal processing, and forecasting. They are, essentially, rule-based systems, in which the definition of these rules and fuzzy membership functions is generally based on verbally formulated rules that overlap through the parameter space. They have a great influence over the performance of the system. On the other hand, the Genetic Algorithm is a metaheuristic that provides a robust search in complex spaces. In this work, it has been used to adapt the decision rules of FLCs that define an intelligent traffic signal system, obtaining a higher performance than a classical FLC-based control. The simulation results yielded by the hybrid algorithm show an improvement of up to 34% in the performance with respect to a standard traffic signal controller, Conventional Traffic Signal Controller (CTC), and up to 31% in the comparison with a traditional logic controller, FLC.

See you in Porto!

Charla sobre Ciencia y Videojuegos en la Universidad de Cádiz

El viernes pasado, Pablo García (aka Dr. Fergu) y yo mismo (aka Dr. Mora) dimos con éxito la charla “La Ciencia y los Videojuegos” en la Escuela Superior de Ingeniería de la Universidad de Cádiz.

Fuimos invitados por el Dr. Manuel Palomo Duarte y muy bien acogidos, tanto por él, como por el resto de sus compañeros. ;D

En la primera parte, conté la relación existente entre ciencia y videojuegos (con mi clásica presentación), con una parte centrada en la interacción autoática y la extracción de información en videojuegos para la creación o mejora de aspectos de los mismos (Inteligencia Artificial, Generación Procedural de Contenidos, etc).

La presentación es:

En la segunda parte, Pablo explicó varios de los desarrollos e investigación del grupo GeNeura en el ámbito de los videojuegos, aplicando Algoritmos Evolutivos a juegos como Unreal, Planet Wars, Super Mario o StarCraft.

Su presentación es:

Esperamos que os gustase (u os guste, si las veis ahora). ;)

Ms. PacMan in IEEE Transactions on CI and AI in Games

Our fans and followers must be happy! ;D

They can now access the excellent work by Federico Liberatore in IEEE ToCIAIG journal.

This is the best journal concerning Artificial Intelligence in games, with a very strict reviewing process, so, we are very proud of this success. ;)

This is the next step in the research started one year and a half ago designing competitive  Ghost Teams for catching Ms. PacMan.

The abstract is:

In the last year, thanks to the Ms. Pac-Man vs Ghosts competition, the game of Ms. Pac-Man has gained increasing attention from academics in the field of Computational Intelligence. In this work, we contribute to this research stream by presenting a simple Genetic Algorithm with Lexicographic Ranking (GALR) for the optimization of Flocking Strategy-based ghost controllers. Flocking Strategies are a paradigm for intelligent agents characterized by showing emergent behavior and for having very little computational and memory requirements, making them well suited for commercial applications and mobile devices. In particular, we study empirically the effect of optimizing homogeneous and heterogeneous teams. The computational analysis shows that the Flocking Strategy-based controllers generated by the proposed GALR outperform the ghost controllers included in the competition framework and some of those presented in the literature.

CoSECiVi 2015 ya está en marcha

La segunda edición del Congreso de la Sociedad Española para las Ciencias del Videojuego ya está en marcha.

La web del mismo es: http://gaia.fdi.ucm.es/sites/cosecivi15/

Al igual que el año anterior, este congreso pretende ser un foro científico para el intercambio de ideas y resultados sobre el diseño, la ingeniería y la teoría de la tecnología aplicada al entretenimiento en España. Por tanto, en él se abordarán temas de inteligencia artificial, informática gráfica, e ingeniería del software entre otros, así como su aplicación en cuestiones de diseño y en otras ramas como la enseñanza, la medicina, la comunicación o el arte, por ejemplo.

Al igual que en la edición anterior , se ha llegado a un acuerdo con la organización del GameLab 2015 para que el congreso se celebre en su mismo entorno (habrá inscripción conjunta), y se está trabajando para que el CoSECiVi se integre totalmente dentro del GameLab, siendo una parte parte de las actividades del mismo y celebrándose en su misma sede. Esto dará un gran impulso al congreso y lo acercará aún más a la industria del videojuego en nuestro país. :D

Al igual que el año pasado habrá cuatro posibles categorías para los artículos a enviar, que podrán escribirse en español o en inglés:

  1. Trabajos Regulares: Trabajos que muestren resultados de investigación. Éstos pueden tener una extensión máxima de 12 páginas en formato LNCS.
  2. Trabajos Emergentes: Nuevas ideas de investigación que pueden ser enriquecidas a través de la discusión con la comunidad SECiVi. Estos trabajos deberán tener una extensión máxima de 10 páginas en formato LNCS.
  3. Demostración de herramientas: Esta opción está orientada a la presentación de herramientas que soporten de forma práctica las propuestas teóricas. Las propuestas de demostraciones de herramientas podrán tener una extensión máxima de 6 páginas en formato LNCS.
  4. Divulgación de Trabajos Relevantes ya Publicados: Este apartado busca dar a conocer trabajos de investigación con altos índices de calidad y de especial relevancia para la comunidad SECiVi. Estas propuestas, en su versión definitiva (la que se publicará en la actas del congreso), podrán tener una extensión máxima de 6 páginas en formato LNCS, resumiendo el contenido del trabajo que pretende darse a conocer.

Como colofón, se hará una selección de los mejores trabajos (escritos en inglés) para su posible publicación en un número especial de la revista Entertainment Computing de Elsevier

¡Esperamos vuestros trabajos! ;D
