Basically, you have to throw away everything to the left of the rightmost wildcard when operating that rule. Consider the _badChar array gives you offsets to move the search position quickly where the character that you see at the current haystack position is not …

Calculating Boyer Moore Bad Character Table with examples
WebAug 31, 2006 · 99 ev Aarhus, September 1 by Abstract We present the first derivation of the search phase of the Boyer–Moore string-matching algorithm by partial evaluation of an inefficient string matcher. The derivation hinges on identifying the bad-character-shift heuristic as a binding-time improvement, bounded static variation. WebBoyer-Moore: Good suffix rule Like with the bad character rule, the number of skips possible using the good suffix rule can be precalculated into a few tables (Gus"eld 2.2.4 and 2.2.5) Rule on previous slide is the weak good suffix rule; there is also a strong good suffix rule (Gus"eld 2.2.3) T: P: CTTGCCTACTTACTTACT CTTACTTAC t CTTACTTAC ...
