FFT-based algorithms for the string matching with mismatches problem

WebOne particular approach to string matching problem is the semi-numerical approach of viewing pattern matching as the process of multiplying polynomials. A classical tech-nique used for speeding up multiplication is the convolution method which uses Discrete Fourier Transform and its in-verse. The Fast Fourier Transform algorithm can be used WebJun 30, 2015 · There's two similar operations you can perform with FFT: convolution and correlation. Convolution is used for determining how two signals interact with each-other, whereas correlation can be used to … dj nimoy

WebThe string matching with mismatches problem requires finding the Hamming distance between a pattern P of length m and every length m substring of text T with length n. … WebJun 28, 2009 · We develop a method for performing boolean convolutions efficiently in word RAM model of computation, having a word size of w=Ω (logn) bits, where n is the input size. The technique is applied to... WebKey words: Algorithms; String matching; Wildcards. 1 Introduction The problem of determining the time complexity of exact matching with wild-cards has been well studied. Fischer and Paterson [2] presented the first solu-tion based on fast Fourier transforms (FFT) with an O(nlogmlog Σ ) time algorithm in 1974. dj nikki
