I have had a quick look. It seems that you've implemented the Needleman-Wunsch
algorithm, which takes quadratic time and space. There are less
at least for similar input sequences, e.g. Myers - "An O(ND) Difference Algorithm
and Its Variations"; I have an implementation of that here:
http://svn.chezphil.org/anyterm/trunk/src/diff.cc & .hh.
What is your motivation for choosing Needleman-Wunsch?
