There are two compelling reasons to use a computational model (i.e. simulation) to
study the mutational meltdown process. First, the analytical
models are based on making several simplifying assumptions that
hold only for large values of **K** or other parameters, and we
are most interested in the predicted extinction of endangered
species where **K** is small. Second, the analytical models developed
so far are
accurate only for the middle, or ``buildup'', phase of mutation accumulation.

In this section we will describe two computational models for mutational meltdown. The simulator for asexual reproduction is fairly simple and can be designed and implemented with about a week's work. Extending the simulator for sexual reproduction requires another two to three works effort.
