Optimal Foraging in Groups

A common assumption of optimal foraging theory is that natural selection has favoured animals that forage in an optimal way, as such an ability increases the individual’s probabillity of survival [4, 5]. This argument is used to support optimality principles in biology, and is at the base of optimal foraging theory [6]. Efficient foraging is clearly beneficial when food is in short supply, but ...

SEMANTIC MEMORY AND OPTIMAL FORAGING 1 Running head: SEMANTIC MEMORY AND OPTIMAL FORAGING Optimal Foraging in Semantic Memory

Do humans search in memory using dynamic local-to-global search strategies similar to those that animals use to forage between patches in space? If so, do their dynamic memory search policies correspond to optimal foraging strategies seen for spatial foraging? Results from a number of fields suggest these possibilities, including the shared structure of the search problems—searching in patchy e...

Optimal Foraging Theory Revisited

Optimal foraging theory explains adaptation via natural selection through quan-titative models. Behaviors that are most likely to be favored by natural selection canbe predicted by maximizing functions representing Darwinian fitness. Optimizationhas natural applications in engineering, and so this approach can also be used to de-sign behaviors of engineered agents. In this thesi...

Unorthodox Optimal Foraging Theory

As the Simulation of Adaptive Behaviour (SAB) eld continues to mature, it is essential that general methodological positions become elaborated into practical programmes of research. This paper describes how a particular avour of SAB modelling the use of genetic algorithms to design situated agent (animat) architectures-can eeec-tively complementòptimal foraging theory', as it is understood in t...
