Modelling group foraging: individual suboptimality, interference, and a kind of matching
نویسنده
چکیده
In this paper a series of agent-based models support the hypothesis that behaviours adapted to a group situation may be suboptimal (or `irrational') when expressed by an isolated individual. These models focus on two areas of current concern in behavioural ecology and experimental psychology: the `interference function' (which relates the intake rate of a focal forager to the density of conspeci cs) and the `matching law' (which formalises the observation that many animals match the frequency of their response to di erent stimuli in proportion to the reward obtained from each stimulus type). Each model employs genetic algorithms to evolve foraging behaviours for multiple agents in spatially explicit environments, structured at the level of situated perception and action. A second concern of this paper is to extend the understanding of both matching and interference per se by modelling at this level.

Mathematical Model of Foraging in a Group of Robots: Effect of Interference
In multi-robot applications, such as foraging or collection tasks, interference, which results from competition for space between spatially extended robots, can signi cantly a ect the performance of the group. We present a mathematical model of foraging in a homogeneous multi-robot system, with the goal of understanding quantitatively the e ects of interference. We examine two foraging scenario...
متن کاملDistribution Modeling of Foraging Habitats for Egyptian Vulture (Neophron percnopterus) in Kermanshah Province, Iran
The Egyptian vulture, Neophron percnopterus, as a globally endangered species, is significantly affected by conflicts with human, leading to the decline of this species population. Availability of food resources is known as one of the most important factors affecting the distribution of the Egyptian vulture. In this study, we employed an ensemble modelling approach to predict the suitability o...
متن کاملSpatially Explicit Models of Forager Interference
In behavioural ecology the ‘interference function’ relates the intake rate of a focal forager to the density of conspecifics, and has been (and remains) the subject of extensive theoretical and empirical activity. This paper describes a novel agent-based model of interference characterised by the use of genetic algorithms to evolve foraging behaviours in a spatially explicit environment. This m...
متن کاملMobility, Competition, and Plio-Pleistocene Hominid Foraging Groups
Evidence for carcass access times and levels of early hominid mobility is synthesized using studies of carnivore ethology and theories of interspecific competition to arrive at tentative conclusions about the organization of Plio-Pleistocene hominid foraging groups. The model presented suggests that group foraging tactics, in combination with high mobility, are central to successful confrontati...
