Arms Races and Car Races

Evolutionary car racing (ECR) is extended to the case of two cars racing on the same track. A sensor representation is devised, and various methods of evolving car controllers for competitive racing are explored. ECR can be combined with co-evolution in a wide variety of ways, and one aspect which is explored here is the relative-absolute fitness continuum. Systematical behavioural differences ...

Investigation of parameters affecting the travel time at tramway systems: the case of Athens, Greece

Within the framework of this paper, various parameters that might affect the efficiency and the reliability of a tramway system are examined. Two linear regression models are built in order to investigate the way these parameters are affecting the commercial speed and the travel time deviation, respectively. The case study is the tramway of Athens which operates since the 2004 Olympic Games. Al...

On extreme daily precipitation totals at Athens, Greece

The paper studies changes in daily precipitation records at the National Observatory, Athens, during the period 1891–2004. This is the longest available time series of precipitation for Greece. The results show that both the shape and scale parameter of a fitted two parameter gamma distribution for the last two decades do show a significant difference of these parameters, when compared to any p...
