Trace Repair Never Loses to Classical Repair: Exact and Explicit Helper Nodes Selection

Trace Repair Never Loses to Classical Repair: Exact and Explicit Helper Nodes Selection
We study the repair of Reed--Solomon codes over $\mathbb{F}=\mathbb{B}^t$ using traces over $\mathbb{B}$. Building on the trace framework of Guruswami--Wootters (2017), recent work of Liu--Wan--Xing (2024) reduced repair bandwidth by studying a related subspace $\mathcal{W}_k$. In this work, we determine the dimension of $\mathcal{W}_k$ exactly using cyclotomic cosets and provide an explicit set of helper nodes that attains bandwidth $(n-d-1)\log |\mathbb{B}|$ bits with $d=\text{dim}(…

openflights: Openflights airport network
A network of regularly occurring flights among airports worldwide, extracted from the openflights.org dataset. Nodes represent airports, and direction of edge (i,j) indicates a regularly occurring commercial flight by a particular airline from airport i to airport j. Multiple edges may exist between a pair of airports if multiple airlines offer that flight, or if one airline offers multiple such flights each day.
This network has 3214 node…
