  We deal with stochastic network simulations in a model with three distinct
species that compete under cyclic rules which are similar to the rules of the
popular rock-paper-scissors game. We investigate the Hamming distance density
and then the basin entropy behavior, running the simulations for some typical
values of the parameters mobility, predation and reproduction and for very long
time evolutions. The results show that the basin entropy is another interesting
tool of current interest to investigate chaotic features of the network
simulations that are usually considered to describe aspects of biodiversity in
the cyclic three-species model.
