`ergm`

uses a Metropolis-Hastings (MH) algorithm to control the behavior of the Markov Chain
Monte Carlo (MCMC) for sampling networks. The MCMC chain is intended to step around the sample space of
possible networks, selecting a network at regular intervals to evaluate the statistics in the model. For
each MCMC step, *n* (*n=1* in the simple case) toggles are proposed to change the dyad(s) to the
opposite value. The probability of accepting the proposed change is determined by the MH acceptance ratio.
The role of the different MH methods implemented in `ergm`

is to vary how the sets of dyads are
selected for toggle proposals. This is used in some cases to improve the performance (speed and mixing) of
the algorithm, and in other cases to constrain the sample space.
