Optimal Fraction Repetition Codes for Access-Balancing in Distributed Storage
Wenjun Yu, Xiande Zhang, Gennian Ge
To solve the access-balancing problem in distributed storage systems, we introduce a new combinatorial model, called MinVar model for fractional repetition (FR) codes. Since FR cod…
Some New Results on Splitter Sets
Zuo Ye, Tao Zhang, Xiande Zhang +1
Splitter sets have been widely studied due to their applications in flash memories, and their close relations with lattice tilings and conflict avoiding codes. In this paper, we gi…
Bollobás type theorems for hemi-bundled two families
Wenjun Yu, Xiangliang Kong, Yuanxiao Xi +2
Let be a collection of pairs of sets with and for . Suppose that if and only if , then by…
Repairing Generalized Reed-Muller Codes
Tingting Chen, Xiande Zhang
In distributed storage systems, both the repair bandwidth and locality are important repair cost metrics to evaluate the performance of a storage code. Recently, Guruswami and Woot…
Complexity of Dependencies in Bounded Domains, Armstrong Codes, and Generalizations
Yeow Meng Chee, Hui Zhang, Xiande Zhang
The study of Armstrong codes is motivated by the problem of understanding complexities of dependencies in relational database systems, where attributes have bounded domains. A $(q,…
Optimal -Ary Error Correcting/All Unidirectional Error Detecting Codes
Yeow Meng Chee, Xiande Zhang
Codes that can correct up to symmetric errors and detect all unidirectional errors, known as -EC-AUED codes, are studied in this paper. Given positive integers , and…
Covering Radius of Permutation Groups with Infinity-Norm
Xin Wei, Xiande Zhang
The covering radius of permutation group codes are studied in this paper with -metric. We determine the covering radius of the -type group, which is a direct pro…
