Gillespie algorithm

Vanilla C code for the Stochastic Simulation Algorithm

October 24, 2011 | 0 Comments

The Gillespie stochastic simulation algorithm (SSA) is the gold standard for simulating state-based stochastic models. If you are a R buff, a SSA novice and want to get quickly up and running stochastic models (in particular ecological models) that are not … Continue reading → [Read more...]

119 days of number crunching…

August 23, 2007 | 0 Comments

Just checked on the 70000+ simulations I submitted to the Cow last night. The purpose of these runs is to explore a given system (the logistic growth model in this case) using different implementations of the stochastic simulation algorithm (aka … Continue reading →
