Integral Tau Methods for Stiff Stochastic Chemical Systems

Abstract: Tau leaping methods can efficiently simulate models of stiff stochastic chemical systems. However, most existing methods do not naturally preserve some chemical structures, such as integer-valued and nonnegative molecular population states. In this talk, we present structure preserving tau methods for simulating stochastic chemical systems. We illustrate the new methods through a number of biochemically motivated examples, and provide comparisons with existing implicit tau methods.
