Deterministic list decoding of Reed-Solomon codes
Soham Chatterjee, Prahladh Harsha, Mrinal Kumar
We show that Reed-Solomon codes of dimension and block length over any finite field can be deterministically list decoded from agreement in tim…
Algorithmizing the Multiplicity Schwartz-Zippel Lemma
Siddharth Bhandari, Prahladh Harsha, Mrinal Kumar +1
The multiplicity Schwartz-Zippel lemma asserts that over a field, a low-degree polynomial cannot vanish with high multiplicity very often on a sufficiently large product set. Since…
Fast list recovery of univariate multiplicity and folded Reed-Solomon codes
Rohan Goyal, Prahladh Harsha, Mrinal Kumar +1
A recent work of Goyal, Harsha, Kumar and Shankar gave nearly linear time algorithms for the list decoding of Folded Reed-Solomon codes (FRS) and univariate multiplicity codes up t…
Optimal Online Bipartite Matching in Degree-2 Graphs
Amey Bhangale, Arghya Chakraborty, Prahladh Harsha
Online bipartite matching is a classical problem in online algorithms and we know that both the deterministic fractional and randomized integral online matchings achieve the same c…
An exposition of recent list-size bounds of FRS Codes
Abhibhav Garg, Prahladh Harsha, Mrinal Kumar +2
In the last year, there have been some remarkable improvements in the combinatorial list-size bounds of Folded Reed Solomon codes and multiplicity codes. Starting from the work on…
