In nature species interact among each other in many ways. The most common and studied interaction is that between a predator and its prey. A food web can be defined as a network of interactions that describes who eats whom in a certain ecosystem and at a certain time of the year.

This is a beautifully simple ecological network model that can simulate predator-prey and competitive multispecies dynamics. This is the B model of the paper 1, I read it long ago and for many years I wanted to make a version of it, finally, I did it.

SNIM This is a C++11 implementation of a stochastic multispecies model. The model has multiple applications to investigate the relationship between ecological interactions (competition, predation) and diversity. It involves a discrete definition of individuals belonging to a given set of species.
