Left: Cell Segregation Indicator (CSI) v. Disallowed-Realised Ratio. Right: Average Population distribution across all M = 50 cells for different values of βmove (Fraction of total population in each cell). Black Dashed Line: Fully homogeneous distribution. Blue: βmove = 1000. Green: βmove = 100. Red: βmove = 10. Cyan: βmove = 5.
