The original algorithms in the MUMMER software package were designed by Art Delcher, Simon Kasif and Steven Salzberg.
The system is maintained primarily by Steven Salzberg and Arthur Delcher at Center for Computational Biology at Johns Hopkins University.
The gaps fall in the following four classes:[4] This algorithm was redesigned to require less memory and increase speed and accuracy.
The improvement was the amount stored in the suffix trees by employing the one created by Kurtz.
[6] According to Guillaume and his team, there are some extra improvements in the implementation and also innovation with Query parallelism.
