Chien search is an efficient algorithm used for finding factors of polynomials, particularly in the context of error correction codes, such as Reed-Solomon codes. It is named after the mathematician Tsun-Hsing Chien. Here's a high-level overview of how it works: 1. **Polynomial Representation**: In error correction coding, data is typically represented as a polynomial over a finite field.
