<p>Mixed -updating on a graph.</p>

In this illustration <i>N</i> = 7 and four of them are mutants. The orange vertices are mutants and the blue vertices are wild-type individuals.

At each time step, a dB step occurs with probability , and with the remaining probability a Bd step occurs. The thick arrows on the edges of the graph are oriented such that the arrowheads indicate the possible location(s) of death. The arrow tails indicate the possible location(s) of birth for each time step.
