During SEARCH, a forager’s decision to EAT a given resource item is determined by its (i) exploration tendency P E (see below), (ii) personal information about the rewards associated with that resource type (a ir), and (iii) whether the forager has been socially stimulated by seeing another forager eat that resource type P S (see below). During evaluation of a resource item, these three factors come together to determine the probability P F to choose to eat that item as follows: 1\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$ {\begin{aligned} { P_{F} =} P(r | a_{ir}, a_{ie}, \sigma_{i}, P_{E}, P_{S}) = min\left[ 1.0, \left(\frac{a_{ir}}{a_{ie}} \right)^{\sigma_{i}} + P_{E} + P_{S} \right] \end{aligned}} $$ \end{document}PF=P(r|air,aie,σi,PE,PS)=min1.0,airaieσi+PE+PS
