The study leverages Reinforcement Learning (RL) to model agents that optimize actions based on rewards. It contrasts model-free RL (learning from direct experience) with model-based RL (building internal world models to predict future states), highlighting the latter's advantage in complex tasks like foraging.
Central to the findings is the concept of world models: compact predictive representations of the environment. These models allow AI agents to anticipate future events, plan strategies, and make decisions consistent with the Marginal Value Theorem (MVT), mimicking biological foragers' anticipatory behaviors.
The paper uses the Marginal Value Theorem (MVT) as an optimality model for patch foraging. It describes how agents balance resource exploitation in a patch against travel costs to new patches. Model-based agents naturally converge to MVT-aligned strategies, demonstrating ecological optimality.

Leveraging World Models for Adaptive AI
The Challenge: Biological foragers need to make optimal decisions in dynamic environments, balancing immediate gains with future potential. Traditional model-free RL struggles with this anticipatory planning.
Our Solution: This research shows that model-based RL agents, particularly DreamerV2, learn internal world models that predict future states and rewards. This enables them to 'dream' about trajectories and make decisions aligned with ecological optimality principles like the MVT.
Enterprise Impact: By anticipating resource depletion and travel costs, these agents exhibit significantly more adaptive and efficient foraging strategies, demonstrating a key mechanism for explainable and biologically grounded AI.
