The Advantage of Foraging Myopically [PDF]

open access: yesJ. Stat. Mech. 073501 (2018), 2018
We study the dynamics of a \emph{myopic} forager that randomly wanders on a lattice in which each site contains one unit of food. Upon encountering a food-containing site, the forager eats all the food at this site with probability $p<1$; otherwise, the food is left undisturbed.

Neuroscience of foraging [PDF]

open access: yesFrontiers in Neuroscience, 2014
The papers that accompany this Research Topic fall at the intersection of foraging theory and neuroscience. Why does such a topic merit a Research Topic in Frontiers in Decision Neuroscience? And what does foraging theory have to do with decision neuroscience?

Optimal foraging

open access: yesCurrent Biology, 2022
Before visiting your local supermarket, do you write your food shopping list in the order you expect to encounter the items as you walk around, aisle by aisle? This way, you minimise your travel distance, saving time and effort. Many other animals do the same.

How Smart Should a Forager Be? [PDF]

open access: yesJ. Stat. Mech. 033402 (2022), 2022
We introduce an idealized model of an intelligent forager in which higher intelligence corresponds to a larger spatial range over which the forager can detect food. Such a forager diffuses randomly whenever the nearest food is more distant than the forager's detection range, $R$, and moves ballistically towards the nearest food inside its detection ...

CHOICE AND FORAGING [PDF]

open access: yesJournal of the Experimental Analysis of Behavior, 1982
In Experiment 1, six naive pigeons were trained on a foraging schedule characterized by different states beginning with a search state in which completion of a fixed‐interval on a white key led to a choice state. In the choice state the subject could, by appropriate responding on a fixed ratio of three, either accept or reject the schedule of ...

Optimally frugal foraging [PDF]

open access: yesPhysical Review E, 2018
We introduce the \emph{frugal foraging} model in which a forager performs a discrete-time random walk on a lattice, where each site initially contains $\mathcal{S}$ food units. The forager metabolizes one unit of food at each step and starves to death when it last ate $\mathcal{S}$ steps in the past. Whenever the forager decides to eat, it consumes all

Impact of food distribution on lifetime of a forager with or without sense of smell [PDF]

open access: yesPhys. Rev. E 103, 012114 (2021), 2020
Modeling foraging via basic models is a problem that has been recently investigated from several points of view. However, understanding the effect of the spatial distribution of food on the lifetime of a forager has not been achieved yet. We explore here how the distribution of food in space affects the forager's lifetime in several different scenarios.

Optimal foraging strategies can be learned [PDF]

open access: yesNew J. Phys. 26 013010 (2024), 2023
The foraging behavior of animals is a paradigm of target search in nature. Understanding which foraging strategies are optimal and how animals learn them are central challenges in modeling animal foraging. While the question of optimality has wide-ranging implications across fields such as economy, physics, and ecology, the question of learnability is ...

Optimizing a jump-diffusion model of a starving forager [PDF]

open access: yesPhys. Rev. E 98, 052406 (2018), 2018
We analyze the movement of a starving forager on a one-dimensional periodic lattice, where each location contains one unit of food. As the forager lands on sites with food, it consumes the food, leaving the sites empty. If the forager lands consecutively on $s$ empty sites, then it will starve.

Research on Re-Searching: Interrupted Foraging is Not Disrupted Foraging

open access: yesCognitive Research: Principles and Implications, 2023
AbstractIn classic visual search, observers typically search for the presence of a target in a scene or display. In foraging tasks, there may be multiple targets in the same display (or “patch”). Observers typically search for and collect these target items in one patch until they decide to leave that patch and move to the next one.
