Adaptive explicit-implicit tau-leaping method with automatic tau selection.
نویسندگان
چکیده
The existing tau-selection strategy, which was designed for explicit tau leaping, is here modified to apply to implicit tau leaping, allowing for longer steps when the system is stiff. Further, an adaptive strategy that identifies stiffness and automatically chooses between the explicit and the (new) implicit tau-selection methods to achieve better efficiency is proposed. Numerical testing demonstrates the advantages of the adaptive method for stiff systems.

متن کاملExposition and Streamlined Formulation of Adaptive Explicit-Implicit Tau-Leaping∗
The adaptive explicit-implicit tau-leaping method with automatic tau selection [Y. Cao, D. T. Gillespie and L. R. Petzold, J. Chem. Phys., 126(22):224101 (2007)] is a flexible algorithm for accelerated stochastic simulation of chemically reacting systems. It combines the advantages of different simulation schemes and is particularly useful when a system changes its dynamical behavior over time ...
متن کاملStiffness in stochastic chemically reacting systems: The implicit tau-leaping method
We show how stiffness manifests itself in the simulation of chemical reactions at both the continuous-deterministic level and the discrete-stochastic level. Existing discrete stochastic simulation methods, such as the stochastic simulation algorithm and the ~explicit! tau-leaping method, are both exceedingly slow for such systems. We propose an implicit tau-leaping method that can take much lar...
متن کاملConsistency and Stability of Tau-Leaping Schemes for Chemical Reaction Systems
We develop a theory of local errors for the explicit and implicit tau-leaping methods for simulating stochastic chemical systems, and we prove that these methods are first-order consistent. Our theory provides local error formulae that could serve as the basis for future stepsize control techniques. We prove that, for the special case of systems with linear propensity functions, both tau-leapin...
متن کاملTau leaping of stiff stochastic chemical systems via local central limit approximation
Stiffness manifests in stochastic dynamic systems in a more complex manner than in deterministic systems; it is not only important for a time-steppingmethod to remain stable but it is also important for the method to capture the asymptotic variances accurately. In the context of stochastic chemical systems, time stepping methods are known as tau leaping. Well known existing tau leaping methods ...
