- We examine the structure of pseudocodewords in Tanner graphs and derive lower bounds of pseudocodeword weights.2004, IEEE International Symposium on Information Theory, page 67:
- Other notions of pseudocodeword-like structures such as stopping sets are also known to coincide with these polytope vertices.2008, Ming-Yang Kao, Encyclopedia of Algorithms, page 481:
