Description
Each of the 64 spaces on the checkerboard represents a territory that can be occupied by a member of a population. One type of marker indicates which territories are occupied, and the other type indicates which territories are available for the next time step. Each of 9 time steps has two stages, a stage in which die rolls are used to determine which of the available territories becomes occupied in that time step and a stage in which newly available territories are identified. Occupied squares remain occupied for the whole experiment, while available squares remain available until eventually becoming occupied. The data for the experiment is a list of population counts at the end of each time step.
