WebJun 15, 2016 · However, it is non-trivial to calculate the mean-first passage time for non-Markovian systems analytically (see e.g. ). But because the main purpose of this example is to investigate how well the IIA equations work for non-Markovian systems we will for simplicity extract from simulations as the reciprocal of the mean first-passage time.
