aho-corasick

Is there an algorithm like Aho-Corasick , which can match a set of patterns simultaneously and is applicable to be used in anti-malware comparison? Do all known commercial antivirus software use the Aho-Corasick algorithm? What are the advantages of the Aho-Corasick algorithm over Boyer-Moore ? parapura rajkumar Boyer-Moore : For searching one string in another target string Aho-Corasick : For searching multiple patterns simultaneously So the advantage being that Aho-Corasick is optimal if you want to search lot of patterns simultaneously in one pass. Rabin-Karp string search can also match

I have a trouble with understanding this implementation of the Knuth-Morris-Pratt algorithm in Haskell. http://twanvl.nl/blog/haskell/Knuth-Morris-Pratt-in-Haskell In particular I don't understand the construction of the automaton. I know that it uses the "Tying the Knot" method to construct it, but it isn't clear to me and I also don't know why it should have the right complexity. Another thing I would like to know is whether you think that this implementation could be easily generalized to implement the Aho-Corasick algorithm. Thanks for your answers! So here's the algorithm: makeTable :: Eq

Please help me to understand the construction of state transition table for more than one patterns in the Aho-Corasick algorithm. Please give a simple and detailed explanation so that I could understand. I am following this paper and here is the animation for that. Thanks. Phase 1 Creating the keyword tree : Starting at the root, follow the path labeled by chars of P i If the path ends before P i , continue it by adding new edges and ... nodes for the remaining characters of P Store identifier i of P i at the terminal node of the path I demonstrate it by an example : Suppose we have a finite
