Example of the derivation of the joint potential path area (when Ï•=10). Circles and squares represent locations of two different individuals; the numbers inside represent the time sequence. The grey scales of the ellipses correspond to the time intervals used for their computation: from light grey for the [1,2] interval to dark grey for the [3,4] interval. The black regions with white dashed borders correspond to the potential meeting areas
