 The tau-leaping method thus has the advantage of simulating many transitions in one leap while not losing significant accuracy, resulting in a speed up in computational time.This method approximates reversible processes (which includes random walk/diffusion processes) by taking only net rates of the opposing events of a reversible process into account.The main advantage of this method is that it can be implemented with a simple if-statement replacing the previous transition rates of the model with new, effective rates.
