Boyer moore algorithm good suffix table
WebNote: The bad-character shift can be negative. Since for shifting the characters, the Boyer-Moore algorithm applies the maximum (skip characters) between the good-suffix shift and bad-character shift. Good-Suffix Shift. Let, t substring matched by inner loop, then skip characters until: There are no mismatches between P and t. P moves past t. http://www.csc.villanova.edu/~mdamian/csc8301/notes/Lec9.pdf

The actual shifting offset is the maximum of the shifts calculated by these rules. The bad-character rule considers the character in T at which the comparison process failed (assuming such a failure occurred). The next occurrence of that character to the left in P is found, and a shift which brings that occurrence in line with the mismatched occurrence in T is propose… greater lebanon wikipediaWebOct 31, 2024 · A Computer Science portal for geeks.
