A quantitative narrative on movement, disease and patch exploitation in nesting agent groups

Wayne M. Getz; Richard Salter; Krti Tallam

Recall that the quantities c γ,δ,m (t), m = 1, ..., M , contain a fading memory of how many individuals from colony m have visited the cell c γ,δ up until time t. In our implementation these data are stored in an M -element array in the Sequence Cell Memory. This array is initialized with each slot set to 0. At each point in time first the current value of each slot is aged by a factor of e −η M (where η M is represented in the program by the parameter mem fade), and then the current population of the cell is distributed to the slots based on their nest of origin.
