Comment on 'Stiffness in stochastic chemically reacting systems:The implicit tau-leaping method' [J.Chem.Phys.119,12784 (2003)]

摘要

In the Appendix of the paper by Rathinam et al,lthe authors correctly derive expressions for the expected value and variance of the number of S_1 molecules in the first order reversible reaction S_1<->S_2.We show that the same expressions can be obtained by using the generating function in solving the master equation.
