Description

We start with a model where the bacteria are trying to maximize the long-term access to a chemoattractant and,
using results in gambling thermodynamics, we get a boundary for the drift speed that is linear in the information
rate. This boundary becomes relevant at extremely low chemoattractant concentrations.
