Hi Russell Standish
I should stay away from discussing bacteria. Brownian motion and
chemical actions could in fact make intelligence ("free" choice-making)
unnecessary, as you may have suggested.

The algorithm employed by certain bacteria is to travel in a straight
line if nutrient concentration is below a certain threshold, and to
tumble randomly if the nutrient concentration is above a certain
threshold.
Why is this effective? Ballistic motion (straight line case) exhibits
<\Delta x> proportional to <\Delta t> (average position change is
proportional to time), so its a good way to somewhere where resources
are more plentiful. By contrast chaotic motion has <\Delta x>
proportional to , which means you stick around longer
and hoover up more of the good stuff.
Is this autonomous? You bet. Is it living? Yes - it's bacteria, although
a robot doing the same thing would not necessarily be living. Is it
intelligent? - nup.
Cheers
