Frequently Asked Questions

How big does the number of particles needs to be?

This number does not have to be equal to the number of persons in the city, all parameters are normalized using the number of particles, therefore above a minimum value to stabilize the intrinsic randomness of the model all results should be the same (at least the mean result), but in practice there is some issues with rounding on the normalization (that are actively been worked on), to negate those issues one should use the smallest number of particles that spawns exactly one instance of the lest common service (usually hospitals), this can be calculated by \eqref{eq:nparticles}.

$$\begin{equation} Npaticles = \frac{population}{number\_of\_hospitals} \label{eq:nparticles} \end{equation}$$
