Combinatorial batch codes were defined by Paterson, Stinson, and Wei as purely combinatorial versions of the batch codes introduced by Ishai, Kushilevitz, Ostrovsky, and Sahai. There are \begin{document}$n$\end{document} items and \begin{document}$m$\end{document} servers, each of which stores a subset of the items. A batch code is an arrangement for storing items on servers so that, for prescribed integers \begin{document}$k$\end{document} and \begin{document}$t$\end{document} , any \begin…

Erasure combinatorial batch codes based on nonadaptive group testing
TLDR
Based on nonadaptive group testing, three classes of erasure combinatorial batch codes are obtained which allow for the retrieval of any set of a limited number of items even in presence of server failures, but also balance the load among the servers when retrieving.
Lower Bounds for Total Storage of Multiset Combinatorial Batch Codes Using Linear Programming
TLDR
This study forms linear programs so that the optimal solutions provide lower bounds on the total storage of multiset combinatorial batch codes and showed that these lower bounds are either tight or asymptotically tight by constructing the corresponding codes.

Combinatorial batch codes
TLDR
This paper focuses on batch codes, which were introduced by Ishai, Kushilevitz, Ostrovsky and Sahai in [4], and presents batch codes that are optimal with respect to the storage requirement, denoted by N.
Optimal batch codes: Many items or low retrieval requirement
TLDR
The goal is to determine the minimum N(n,k,m) of F, the union of any $i$ members of $\mathcal F$ has cardinality at least $i, for every $1\le i\le k$ for all combinatorial batch codes.
Combinatorial batch codes and transversal matroids
TLDR
An important connection is established between combinatorial batch codes and transversal matroids, and this connection is exploited to characterize optimal combinatorian batch codes if $n=m+1$ and $n =m+2$.
Multiset combinatorial batch codes
TLDR
This paper gives a necessary and sufficient condition for the existence of multiset combinatorial batch codes (MCBCs), and presents several bounds on N(n, k, m, t; r) and constructions of MCBCs.
Relaxations of Hall's condition: Optimal batch codes with multiple queries
TLDR
The first nontrivial results on combinatorial batch codes with t > 1 are obtained, which can be considered equivalently as minimum total size ∑FєF |F| over all set systems F of given order m and size n, which satisfy a relaxed version of Hall's Condition.
Fractional Repetition and Erasure Batch Codes
TLDR
Fractional repetition batch (FRB) codes which provide both uncoded repairs and parallel reads of subsets of stored symbols and erasure combinatorial batch codes (ECBCs) are obtained.
Batch codes and their applications
TLDR
This work demonstrates the usefulness of batch codes by presenting two types of applications: trading maximal load for storage in certain load-balancing scenarios, and amortizing the computational cost of private information retrieval (PIR) and related cryptographic protocols.
