Simulation of clusters up to 215= 32768 cells
M. Eden, 1961
”It is to be seen that the colony is essentially circular in outline. Needlessto say, there are a number of properties of each growing colony as wellas properties of the ensemble that may be worth examining, for example,moments, the eccentricity of the configurations, the roughness of the edge.”
