IONTW: Infection On NeTWorks

IONTW uses the NetLogo programming language, which was developed by Uri Wilensky at The Center for Connected Learning and Computer-Based Modeling.

IONTW simulates both discrete and continuous time agent-based models of infectious disease dynamics on networks. It can simulate models of type SEIR, SIR, SEI, SI, SEIS, and SIS.

Supported network types include: complete graphs, empty graphs, Erdös-Rényi, nearest-neighbor (1 and 2 dimensions), small world (1 and 2 dimensions), preferential attachment, generic scale-free, spatially clustered, random regular, trees, as well as approximately uniform realizations from custom degree sequences and custom distributions.

CSimplex

CSimplex is a plugin for Geomview that allows for the visualization of carrying simplices in n-dimensional competitive Lotka-Volterra systems. This software can compute the carrying simplex, numerical trajectories, and nullclines of the system.
