Features of Pattern Searching Algorithm

  • Pattern searching algorithms should recognize familiar patterns quickly and accurately.
  • Recognize and classify unfamiliar patterns.
  • Identify patterns even when partly hidden.
  • Recognize patterns quickly with ease, and with automaticity.

Introduction to Pattern Searching – Data Structure and Algorithm Tutorial

Pattern searching is an algorithm that involves searching for patterns such as strings, words, images, etc.

We use certain algorithms to do the search process. The complexity of pattern searching varies from algorithm to algorithm. They are very useful when performing a search in a database. The Pattern Searching algorithm is useful for finding patterns in substrings of larger strings. This process can be accomplished using a variety of algorithms that we are going to discuss in this blog.

Naive Pattern Searching algorithm

Naive pattern searching is the simplest method among other pattern-searching algorithms. It checks for all characters of the main string to the pattern. This algorithm is helpful for smaller texts. It does not need any pre-processing phases. We can find the substring by checking once for the string. It also does not occupy extra space to perform the operation....
