- 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.
- Knuth-Morris-Pratt (KMP) exact pattern-matching algorithm Classic algorithm that meets both challenges • linear-time guarantee • no backup in text stream Basic plan (for binary alphabet) • build DFA from pattern • simulate DFA with text as input No backup in a DFA Linear-time because each step is just a state change 9 Don Knuth Jim.

1. Presented By:- Ashika Pokiya(12TI083) Guide by:- Nehal Patel STRING MATCHING ALGORITHMS 2. WHAT IS STRING MATCHING • In computer science, string searching algorithms, sometimes called string matching algorithms, that try to find a place where one or several string (also called pattern) are found within a larger string or text. 3 If the extrema are used as part of the pattern matching, you can calculate them once and store it in the View object, and use them like this: bool pattern (View &data) { return (data.max () - data.min ()) > 1.0; } In summary, the idea is to decouple your data structure as much as possible from the matching functions Pattern Matching 3 Brute-Force Algorithm The brute-force pattern matching algorithm compares the pattern P with the text T for each possible shift of P relative to T, until either n a match is found, or n all placements of the pattern have been tried Brute-force pattern matching runs in time O(nm) Example of worst case: n T = aaa ah n P = aaa

Pattern-matching algorithms scan the text with the help of a window, whose size is equal to the length of the pattern. The first step is to align the left ends of the window and the text and then compare the corresponding characters of the window and the pattern; this procedure is known as attempt The KMP Algorithm is an efficient exact pattern searching algorithm and is used where fast pattern matching is required but there is a drawback. For differnt patterns and text KMP has to be applied multiple times. So, it is not feasible in case of multiple patterns or texts. In that case, more advanced data structures like: Trie, Suffix Trees.

A data structure tries to structure data! Usually more than one piece of data. Should define legal operations on the data. The data might be grouped together (e.g. in an linked list) When we define a data structure we are in fact creating a new data type of our own. i.e. using predefined types or previously user defined types More recently optimal pattern-matching algorithms have been applied to voice and image analysis, as well as to the data mining of scientific simulations of physical phenomena. The Smith-Waterman (SW) algorithm is a dynamic programming algorithm for finding the optimal alignment between two sequences once the relative penalty for mismatches and. ** It preporcesses the pattern and creates different arrays for both heuristics**. At every step, it slides the pattern by max of the slides suggested by the two heuristics. So it uses best of the two heuristics at every step.

Wildcard Pattern Matching: Given a string and a pattern containing wildcard characters, i.e., * and ?', where ? can match to any single character in the string and * can match to any number of characters including zero characters, design an efficient algorithm to find if the pattern matches with the complete string or not. For example Patterns that include structural or relational information are difficult to quantify as feature vectors. Syntactic pattern recognition uses this structural information for classification and description. Grammars can be used to create a definition of the structure of each pattern class

For the previous example HAVANABANANA, we can construct a suffix trie:. Suffix tries are created for the text and are usually done as part of a pre-processing step. After that, searching for patterns can be done quickly by finding a path matching the pattern sequence The fundamental string searching (matching) problem is defined as follows: given two strings - a text and a pattern, determine whether the pattern appears in the text. The problem is also known as the needle in a haystack problem In 1973, Peter Weiner came up with a surprising solution that was based on suffix trees, the key data structure in pattern matching.
