Combinatorial batch codes [PDF]

open access: yesAdvances in Mathematics of Communications, 2009
In this paper, we study batch codes, which were introduced by Ishai, Kushilevitz, Ostrovsky and Sahai in [4]. A batch code specifies a method to distribute a database of [n] items among [m] devices (servers) in such a way that any [k] items can be retrieved by reading at most [t] items from each of the servers.

Combinatorial Gray Codes

SIAM Journal on Computing, 1980
We consider families $\{ {\bf C}(n,k):O \leqq k \leqq n\} $ where each ${\bf C}(n,k)$ is a set of combinatorial objects, $C(n,k) = |{\bf C}(n,k)|$ satisfies a recursion $C(n,k)= a_{n,k}C(n - 1,k - 1) + b_{n,k} C(n - 1,k)$, and each object in ${\bf C}(n,k)$ is represented by an n-vector. We study “loop-free” or “uniformly bounded transition” algorithms,
