What Is Gillespie Algorithm?

In probability theory, the Gillespie algorithm generates a statistically correct trajectory of a stochastic equation system for which the reaction rates are known.

What does the Gillespie algorithm do?

In probability theory, the Gillespie algorithm (or occasionally the Doob-Gillespie algorithm) generates a statistically correct trajectory (possible solution) of a stochastic equation system for which the reaction rates are known. ... It is used heavily in computational systems biology.

What is propensity function?

– Propensity function describes the probability while reaction rate describes the changing rate. – Propensity functions are defined based on population of species while. the reaction rates are defined based on the concentration of species. • Connection. – For simple system, they have similar format.
