Group Divisible Codes and Their Application in the Construction of Optimal Constant-Composition Codes of Weight Three
Yeow Meng Chee, Gennian Ge, Alan C. H. Ling
The concept of group divisible codes, a generalization of group divisible designs with constant block size, is introduced in this paper. This new class of codes is shown to be usef…
The fine intersection problem for Steiner triple systems
Yeow Meng Chee, Alan C. H. Ling, Hao Shen
The intersection of two Steiner triple systems (X,A) and (X,B) is the set A intersect B. The fine intersection problem for Steiner triple systems is to determine for each v, the se…
The Sizes of Optimal q-Ary Codes of Weight Three and Distance Four: A Complete Solution
Yeow Meng Chee, Son Hoang Dau, Alan C. H. Ling +1
This correspondence introduces two new constructive techniques to complete the determination of the sizes of optimal q-ary codes of constant weight three and distance four.
Optimal Memoryless Encoding for Low Power Off-Chip Data Buses
Yeow Meng Chee, Charles J. Colbourn, Alan C. H. Ling
Off-chip buses account for a significant portion of the total system power consumed in embedded systems. Bus encoding schemes have been proposed to minimize power dissipation, but…
On Extremal k-Graphs Without Repeated Copies of 2-Intersecting Edges
Yeow Meng Chee, Alan C. H. Ling
The problem of determining extremal hypergraphs containing at most r isomorphic copies of some element of a given hypergraph family was first studied by Boros et al. in 2001. There…
The PBD-Closure of Constant-Composition Codes
Yeow Meng Chee, Alan C. H. Ling, San Ling +1
We show an interesting PBD-closure result for the set of lengths of constant-composition codes whose distance and size meet certain conditions. A consequence of this PBD-closure re…
