Tau-Leaping Implementations outside of chemistry

Abstract
Tau-leaping is an algorithm for model simulations most often used in kinetic chemistry. It was
created to make simulations more efficient at the cost of some accuracy. However, its uses outside
of chemistry are limited but could help make some model simulations more efficient. This study
aimed to implement Tau-leaping and analyze it from a statistical perspective. The Lotka-Volterra
prey-predator and SIR models were used to implement Tau-leaping and compared to the exact
SSA version. The result was greatly improved run times at the cost of some accuracy. Since these
models’ purpose is to understand the evolution and trends in a population, the loss of accuracy
wasn’t detrimental. The conclusion then became that Tau-leaping is... (More)
