This paper proposes the bacterial foraging meta-heuristic algorithm for multiobjective optimization. In this … multiobjective bacterial foraging optimization technique, the most recent bacterial locations are obtained by chemotaxis process …

information foraging in a problem space. Complementary to epidemiological models of diffusion, foraging-based conceptualizations …

We consider a world in which the mode of food production, foraging or agriculture, is endogenous, and in which … a one-way transition from foraging to agriculture. <P> Nous étudions un monde dans lequel le choix du mode de production …

experiment, these intervals conformed to a Lévy distribution suggesting that the Lévy flight dynamics that characterize foraging …-law distribution of retrieval intervals approximated the optimal foraging value of 2, the more efficient was the retrieval. At an … abstract dynamical level, foraging for particular foods in one's niche and searching for particular words in one's memory must …

There are both benefits (e.g., social information) and costs (e.g., intraspecific competition) for individuals foraging … in groups. To ascertain how group-foraging goats (Capra hircus) deal with these trade-offs, we asked 1) do goats use … social information to make foraging decisions and 2) how do they adjust their intake rate in light of having attracted by …

Foraging on resources that are fixed in space but that replenish over time, such as floral nectar and pollen, presents … animals with the problem of selecting a foraging route. What can flower visitors such as bees do to optimize their foraging … sequence (so-called "trapline foraging"), which may also enhance their foraging efficiency. A moderate level of optimization …
