SA algorithm as implemented in DAMMIN (left) and DAMMIF (right). An initial starting model 
is refined to yield the best possible fit to the experimental data. In DAMMIN, only one neighbouring model 
is taken into account at a time. If multiple cores or CPUs are available, it is possible to prefetch multiple models in parallel, here shown as , 
, 
. Each prefetched model is then examined and either accepted or rejected, according to the rules of SA.
