Background:

  • Identifying biased regions in biological sequences is crucial for understanding genomic function.
  • Existing methods may not be efficient for large-scale genomic datasets.

Purpose of the Study:

  • To develop and describe an algorithm for finding the longest interval with a specified minimum bias in character sequences.
  • To provide a computationally efficient method for analyzing sequence bias.

Main Methods:

  • The algorithm is based on a method for finding the longest interval with a non-negative sum in numerical sequences.
  • It processes sequences of characters (e.g., DNA bases, amino acids) to identify biased regions.
  • Linear time complexity is achieved in practice and guaranteed for rational biases.
