Definition of a Fuzzy Set Neighborhood of cell Ci,j is global SCA
Gi,j := {(Ck,l, ΥC i ,j, C k ,l) |for all Ck,l Є C, 0 ≤ Υ Ci,j, Ck,l
≤ 1}
C is a set of all cells in the CA.
ΥC i ,j, C k ,l represents an interaction coefficient that controls all possible interactions between a cell Ci,j and its global neighborhood Gi,j.
A function of inter-cell distance and cell population density.
