最終回となる今回は**#8 String pattern matching algorithms (文字列探索アルゴリズム)**です。String pattern matching とは文字列探索とは、ある文字列の中から、別のある文字列を探索することであり、さまざまなアルゴリズムがあります。 ここでは中でも代表的な文字列探索のアルゴリズムの Go ...
The searching results were faster than the traditional algorithms especially small number of patterns and small text sizes.Chouvalit KhancomeVeera Boonjing
As it's important to be clear when discussing the problem of string matching, we can use the meticulous symbols used in Introduction to Algorithms. Text:T[1,...,n]T[1,...,n]. Pattern:P[1,...,m]P[1,...,m]. Thus, asT[i],P[j]∈ΣT[i],P[j]∈Σ, the array of letters...
Exact String Matching Algorithms String-algorithm Preliminary Definitions A string is a sequence of characters. In our model we are going to represent a string as a 0-indexed array. So a string S = ”Galois” is indeed an array [‘G’, ’a’, ’l’, ’o’, ’i’, ’s’]. The...

Finally, we show experimental results comparing our algorithms against previous work. These experiments show that our algorithms are among the fastest for typical text searching, being the fastest in some cases. Although we aim mainly at text searching, we believe that our ideas can be successfully...
