A New Discrete Grid-Based Bacterial Foraging Optimizer to Solve Complex Influence Maximization of Social Networks

Algorithm 2

Novel chemotaxis process.

(1)	For each bacterium in the population
(2)	Calculate the fitness of each bacterium.
(3)	Tumble: generate a vector by equation (7). Transform the chemotactic direction vector into probability by equations (8) and (9).
(5)	Swim: continue to change the node in the probability by equation (10) until the new probability does not dissatisfy the criteria of equation (10).
(6)	End
