Figure 3.

Runtimes of String Matching Algorithms. We compared three exact string matching algorithms from SeqAn with the member function basic_string::find of the standard library, as it was implemented for Microsoft Visual C++. The left figure shows the runtimes (in ms) for searching a DNA sequence (human chromosome 21), the right figure for searching a proteine database. The search pattern was taken randomly from the sequence. The figures show the average time needed to find all occurrences of patterns of a given length.
