KMP_Algorithm_Visualizer

Knuth Morris Pratt Pattern Matching Algorithm Visualizer s similar to the naive substring searching approach: at each step, it compares a pattern with a substring of a text trying to find a complete match. The difference between these two algorithms is how they process the case of mismatched symbols.

The Below Snapshots Represent the Single Word Pattern and Multiword Pattern Search Using KMP Algorithm

• Single Word Pattern:

  • Snapshot 1:

• Multiword Pattern:

  • Snapshot 2:

• For more details, refer to the following:

  • KMP Algorithm Documentation
  • Search Patterns: <pattern> (highlighted text) and <pattern>

Note: The snapshots represent the functionality of the KMP algorithm.

Implementation has a few drawbacks and areas that could be improved....

1. Inefficient Visualization: The visualization updates the table with every single character comparison, which can lead to a large number of rows for long texts or patterns, making it difficult to follow the matching process. Improvement: Implement a more summarized view, where the visualization focuses on significant steps, such as when the pattern moves or a match is found, rather than every single comparison.

2. Basic LPS Computation Visualization: The program does not visualize the computation of the LPS array, which is a crucial part of understanding how the KMP algorithm works. Improvement: Extend the visualization to include how the LPS array is constructed, helping users understand the preprocessing step of the KMP algorithm.

NOTE: Its very crucial in visualizing the KMP algorithm in REAL TIME, I have provided a simple simulation that how the KMP works, So every one can understand quickly.. Thanks!

How to Run the Program in Command Line (Windows/Linux)

Prerequisites: JAVA JRE and JDK (any version)

1. Compile the Java program

   javac KMPVisualizer.java

2. After compiling the program, run it!

   java KMPVisualizer

The steps above should work in both Windows and Linux environments.
