Smart swarming of bacteria occurs when individual's decision is made by adjusting the weight given to information that is shared within swarm.

“[Researchers] discovered how bacteria
collectively gather information about their environment and find an
optimal path to growth, even in the most complex terrains…’Based on confidence in their own information and decisions, bacteria
can adjust their interactions with their peers,’ Prof. Ben-Jacob says. ‘When an individual bacterium finds a more beneficial path, it pays less
attention to the signals from the other cells. But at other times, upon
encountering challenging paths, the individual cell will increase its
interaction with the other cells and learn from its peers. Since each of
the cells adopts the same strategy, the group as a whole is able to
find an optimal trajectory in an extremely complex terrain.’” (Hunka 2011:1)
