WebHorspool’s algorithm determines the size of such a shift by looking at the character c of the text that is aligned against the last character of the pattern. This is the case even if … WebJan 6, 1992 · We study Boyer-Moore-type string searching algorithms. We analyze the Horspool's variant. The searching time is linear. An exact expression of the linearity constant is derived and is proven to be asymptotically α, 1 c ⩽α⩽ 2 (c + 1), where c is the cardinality of the alphabet. We exhibit a stationary process and reduce the problem to a word …
