Stochastic Spatial Simulator

Steve Krone and Yongtao Guan




WinSSS is a Windows-based program for simulating stochastic spatial models that are individual based, have discrete special structure, and continuous time.  These are commonly referred to as Interacting Particle Systems (IPS) and asynchronously-updated Probabilistic Cellular Automata (PCA).  Currently, WinSSS includes the following models:

        1. Cyclic Resource-Species Model
        2. Epidemic Model
        3. Basic Contact Process
        4. Multi-type Contact Process
        5. General Rock-Scissor-Paper Model
        6. Voter Model (Linear and Threshold)
        7. Greenberg-Hastings Model
