## Abstract

> This paper presents an active inference model of ant colony foraging behavior, utilizing a Markov decision process to simulate and analyze the dynamics of trail formation and decision-making in ant colonies. The study aims to integrate insights from behavioral modeling with ecological and evolutionary frameworks to enhance understanding of collective behavior in eusocial insects.

## Keywords

`active inference` · `ant foraging` · `Markov decision process` · `stigmergy` · `T-maze` · `collective behavior` · `behavioral modeling` · `eco-evo-devo`

## Key Contributions

- Introduced an active inference model specifically for ant colony foraging behavior.
- Demonstrated the model's ability to replicate key phenomena such as trail formation in response to food discovery.
- Integrated stigmergic regulation into the active inference framework, enhancing the understanding of collective decision-making.
- Provided a versatile simulation model that can be adapted for various environmental and biophysical manipulations.

## Methods

- Developed a Bayesian simulation model based on active inference principles.
- Utilized a Markov decision process to simulate ant foraging behavior.
- Focused on stigmergic outcomes using a single trail pheromone molecule.
- Conducted in silico experiments to validate the model against established behavioral paradigms.
