The usage of SSA for chemical reactions opens a paradigm in understanting of chemotaxis processes. In [1] the authors introduce a model for the interaction dynamics of
We will extend the Gillespie' SSA from a open-closed-space to a open-closed-grid where each node has its own dynamics and is influenced by its neighbors.
