   Keywords : Bak-Sneppen; Discrete Bak-Sneppen; co-evolution; self-organized criticality; Mathematics and Statistics;

   Abstract : In 1993, Per Bak and Kim Sneppen proposed a model of co-evolution between species, where survival of a particular species affects the survival of its neighbouring species. In the discrete case of the model, each species, or an entry in a set with periodic boundary conditions, is an element x_i ∈ {0, 1}, in the set of size N, where x_i represents the fitness. READ MORE

3. 2. Generalizations of the Discrete Bak-Sneppen Model

   University essay from Lunds universitet/Matematisk statistik

   Author : John Jönsson; [2020]
   Keywords : discrete; Bak-Sneppen; model; generalized; probability; Markov; Mathematics and Statistics;

   Abstract : Consider n vertices arranged in a circle where each vertex is given a fitness from {0,1}. At each discrete time step, one of the vertices with fitness equal to zero (unless there are none of those, then pick a vertex with fitness equal to one) is selected with equal probability. READ MORE
