WebOptimal Foraging Theory. Optimal foraging theory is a topic in behavioral ecology, the field of biology dealing with how behavior contributes to an animal's reproductive success or fitness.

Forage Definition & Meaning - Merriam-Webster

WebUniversity of California, Santa Cruz WebOptimality models are used to predict optimal behavior (ex. time spent foraging). To make predictions about optimal behavior, cost-benefit graphs are used to visualize the optimality model (see Fig 1). Optimality occurs at the point in which the difference between benefits and costs for obtaining a currency via a particular behavior is maximized.
