This assignment is about empirically testing and comparing three exact string matching algorithms for searching strings or patterns in a text document. The algorithms you will have to test and compare are: 1) Boyer-Moore string matching algorithm, 2) Rabin-Karp algorithm, and 3) Knuth-Morris-Pratt algorithm. A variant of the Boyer Moore algorithm uses two heuristics: the bad character heuristic and the good suffix heuristics. You should use this variant of the algorithm. You are free to use Java, C, or C++ to develop your applications for the purpose of testing. You may find onli esources very useful for the purpose. Here is a link to a website that contains implementations of many string ne matching algorithms along with some explanatory notes: www-igm.univ-mlv.fir/-lecroq/string/ Please, be advised that you will invariably need to extend or modify the available source code of a string matching algorithm to suit your needs for the purpose of testing. This may involve some understanding of the given code. Testing: Use a text file containing the Gettysburg Address by President Abraham Lincoln. You may consider or convert all letters in uppercase while processing. For all three algorithms, consider the following patterns of lengths from 3 to 9 for comparison. For each pattern, determine the number of comparison done by the algorithm. a) Five Patterns Pattern Length Ago, war, men, God, new Long, live, dead, work, vain Equal, civil, field, brave, birth Nation, battle, ground, forget, resolve, people Brought, liberty, freedom, measure, resolve Dedicate, remember, advanced, conceive, struggle Conceived, dedicated, struggled, increased, remaining 4 9 b) Comparing Knuth-Morris-Pratt Rabin-Karp Pattern Length Boyer-Moore Average Case Worst Case Worst Case Average Worst Case Average Case Case 4 ntry in the cell of the table must be filled with number of character comparisons divided by the index of the last character compared in the text document with the pattern. For any worst case, choosea pattern of a specific length that does not occur in the text document.
