Program names are given as defined in publications or obtained as personnal communication. Numbers under brackets indicate the frequency of use in successful ab initio structure determination from powder diffraction data (up to 1997 included). This is just a number, not a quality mark, a quantity mark.

Several such operations may be necessary. So one may found Mol+FULLP for instance at step 5. Sometimes however the structure is completed at stage 4.
