I would like to implement a strong seeded randomness extractor for flat sources as a part of my project.
Most of the literature on seeded extractors is concentrated on minimizing seed length. However, low entropy loss is crucial for my construction. What are the known extractors with minimal entropy loss? How efficient is the extractor in practice?
Is there a lower bound on the entropy loss for strong seeded extractors?
Are there any implementations of extractors that I can use off the shelf?
