| Abstract: |
| Foraging theory tries to identify the most efficient strategy of a predator in different environments.
In the last years, more and more attention has been devoted to the analysis of L\`evy-type patterns in animal searches.
We will present several efficiency functionals whose optimality is discussed in relation to the L\`evy exponent of the corresponding evolution equation for the forager. We will also discuss whether or not the optimal L\`evy exponent corresponds to a viable strategy and detect high-gain/high-risk foraging patterns. |
