String matching algorithms are used in finding a pattern in a string. In this paper, the authors have given a novel algorithm to reduce the time complexity of string matching. The proposed algorithm is based on the concept of hashing with chaining. Further, the authors have found reduced time...

4 Conclusions For the standard p-string matching problem, we have derived an algorithm whose complexity is independent of j\Sigmaj, the size of the set of fixed symbols in the p-strings. We have als...Time-space-optimal string matching - Galil, Seiferas - 1983...
In this paper, we propose two new approaches for accurate and efficient privacy-preserving string matching that provide privacy against various attacks. In the first approach we apply hashing-based encoding on sub-strings (q-grams) to compare sensitive strings, while in the second approach we ...

Time complexity is the same as binary search which is logarithmic, O(log2n). This is because every time our search range becomes half.So, T(n)=T(n/2)+1(time for finding pivot) Using the master theorem you can find T(n) to be Log2n. Also, you can think this as a series of...
Multithreaded implementation of hybrid, pattern matching algorithm performs the parallel string searching on different text data by executing a number of threads simultaneously. This approach is advantageous from all other string-pattern matching algorithm in terms of time complexity. This again improves ...
