...Here we present experimental data which allow to compare, in terms of running time, the following string matching algorithms on binary strings and encoded DNA sequences: the Binary-Boyer-Moore algorithm (BBM) [8] by Klein and Ben-Nissan, the Binary-Hash-Matching algorithm (BHM) [5], the BinarySkip-Search algorithm (BSKS) [5], Fed algorithm (FED) [7] and the new Bfl (BFL) algorithm....
