## S4 method for signature 'Bac'
chemotaxis(object, population, j)

Arguments

object

An object of class Bac.

population

An object of class Arena.

j

The number of the iteration of interest.

Details

Bacteria move to a position in the Moore neighbourhood which has the highest concentration of the prefered substrate, which is not occupied by other individuals. The prefered substance is given by slot chem in the Bac object. If there is no free space the individuals stays in the same position. If the concentration in the Moore neighbourhood has the same concentration in every position, then random movement is implemented.
