Dear Sarah,

GA doesn't currently implement checkpointing, but it is not difficult to do.
The program writes all GA models examined up to a point to a .details file, so in order to restart an analysis, one would read this file, repopulate the array of examined models, seed an initial population appropriately and start from there.

Because my code is not commented, it may be tricky to identify all the variables and formats involved, so it may be easiest if I added this functionality and, if you want, commented in the code where it was done.

Best,
Sergei
