Explicit Almost-Optimal $\varepsilon$-Balanced Codes via Free Expander Walks

Jun-Ting Hsieh, Sidhanth Mohanty, Rachel Yun Zhang · 2026

We study the problem of constructing explicit codes whose rate and distance match the Gilbert-Varshamov bound in the low-rate, high-distance regime. In 2017, Ta-Shma gave an explicit family of codes w…
