Cooperative target searching in a diffusion field

The paper investigates the problem of cooperative target searching by autonomous agents. Specifically, the navigational task is to search for a target that is the sources of a chemical diffusion field. Previous studies have shown that the combination of the chemotaxis and biased random walking results in a robust navigational strategy for one agent searching in natural unstable settings. The present study shows that the search efficiency and robustness can be improved by deploying two or more cooperating agents.
