In recent years, several works have demonstrated how the
study of biology can benefit from an algorithmic perspective. In this
talk I discuss a new approach for such a methodology based on
combining theoretical tradeoff techniques with field experiments to
obtain bounds on biological parameters. A proof of concept for this
framework is provided by considering central search foraging
strategies of desert ants, and obtaining theoretical tradeoffs between
the search time and the memory complexity of individuals. Informally,
we show that if the time-competitiveness of the search algorithm is
below $\log k$ then the memory size of individuals (when starting the
search) must be roughly $\log\log k$, where $k$ is the total number of
individuals. Combining such bounds with successful experiments on
living ants would provide a lower bound on the number of states ants
have when commencing the search. Such a lower bound may serve as a
quantitative evidence regarding the quorum sensing mechanism performed
inside the nest.
This talk is based on a recent work with Ofer Feinerman (Weizmann Institute).
