4/27/2012 · Look up Ukkonen's algorithm which builds it in O(n). Also look up the Rabin-Karp algorithm which basically hashes the pattern and compares it with the hash of the search string. Using a rolling hash you can compute the hash as you move along the search string. If the hashes match only then you may compare the strings.

I have been stuck for some time on which is the fastest string search algorithm, heard many opinions, but in the end I'm not sure. I have heard some people saying that the fastest algorithm is Boyer-Moore and some saying that Knuth-Morris-Pratt is actually faster.

In computer science, the Boyer–Moore string-search algorithm is an efficient string-searching algorithm that is the standard benchmark for practical string-search literature. It was developed by Robert S. Boyer and J Strother Moore in 1977. The algorithm preprocesses the string being searched for (the pattern), but not the string being searched in (the text).

Which hashing algorithm is best for uniqueness and speed? Example (good) uses include hash dictionaries. I know there are things like SHA-256 and such, but these algorithms are designed to be secure, which usually means they are slower than algorithms that are less unique. I want a hash algorithm designed to be fast, yet remain fairly unique to ...

Strings and Pattern Matching 3 Brute Force • TheBrute Force algorithm compares the pattern to the text, one character at a time, until unmatching characters are found: - Compared characters are italicized. - Correct matches are in boldface type. • The algorithm can be designed to stop on either the ﬁrst occurrence of the pattern, or upon ...

In BFS and DFS, when we are at a node, we can consider any of the adjacent as next node. So both BFS and DFS blindly explore paths without considering any cost function. The idea of Best First Search is to use an evaluation function to decide which adjacent is most promising and then explore. Best ...

A sorting algorithm is an algorithm made up of a series of instructions that takes an array as input, performs specified operations on the array, sometimes called a list, and outputs a sorted array. Sorting algorithms are often taught early in computer science classes as they provide a straightforward way to introduce other key computer science topics like Big-O notation, divide-and-conquer ...

8/18/2012 · The Knuth-Morris-Pratt string search algorithm is one of these algorithms. Wikipedia entries on algorithms tend to be not very good, but the entry on Knuth-Morris-Pratt string search was quite decent and has very detailed pseudo-code. I translated that pseudo-code more or less directly to the C# language in a class named StringSearcher.

I finally think I've implemented the Knuth–Morris–Pratt string search algorithm correctly, now time for that lovely criticism that causes me to learn! The code doesn't look all that pretty however it does work as far as I've tested. All of what I gathered on this algorithm comes from the Wikipedia page for it. I would appreciate some feedback and suggestions on improvements/errors.
