- The potential for animals to inflict damage on one another whilst competing for indivisible resources is a factor of crucial importance when determining pay-offs to such animals and consequent likelihood of adopting an aggressive resource procurement strategy, a less costly display-based alternative or just a retreat response. Using computer simulations of evolving agents, we assessed the effects of degree of damage potential on social aggression and resource procuring strategies. Furthermore, we assessed the effects of evolving ritualized displays used in contests over resources relative to damage potential. Our results showed that aggressive interactions increased in frequency when the degree of damage potential was low. Ritualized displays tended to reduce aggressive approaches and mortality rate where damage potential was high and low but this was not the case at the intermediate level where aggression and mortality rate increased.

- This article reports on the RoboCup-2003 event. RoboCup is no longer just the Soccer World Cup for autonomous robots but has evolved to become a coordinated initiative encompassing four different robotics events: (1) Soccer, (2) Rescue, (3) Junior (focused on education), and (4) a Scientific Symposium. RoboCup/2003 took place from 2 to 11 July 2003 in Padua (Italy); it was colocated with other sceintific events in the field of AI and robotics. In this article, in addition to reporting on the results of the games, we highlight the robotics and AI technologies exploited by the teams in the different leagues and describe the most meaningful scientific contributions
