+I´m looking for documentation about the Smith-Waterman algorithm. +My intention is to do an implementation of it using C++ with threads. +Any kind of documentation will be helpful. You can find it in many books: - M.S. Waterman "Introduction to computational biology", Chapman & Hall - D. Gusfield "Algorithms on strings, trees, and sequences", Cambridge Univ. Press.
