You're right. What I meant to say is that for any (formal) regular expression, we can compile it to a DFA and then match any strings in time linear in the length of the string. Certainly the pattern length matters both for pre-processing (compiling to DFA) and the runtime in a Boyer-Moore approach. However, as you mentioned in the Boyer-Moore average case of Θ(n/m) a longer pattern is faster, rather than slower as the page on Nevod seems to imply. |
