Sparse Hypercube: A Minimal k-Line Broadcast Graph
This paper proposes a method for reducing the maximum degree of vertices in graphs that maintain optimal broadcast time when a vertex can call a vertex at distance at most k durin...

Sorting-Based Selection Algorithms for Hypercubic Networks
This paper presents several deterministic algorithms for selecting the kth largest record from a set of n records on any n-node hypercubic network. All of the algorithms are based ...

Improved Approximation for the Directed Spanner Problem
We present an O( √ n log n)-approximation algorithm for the problem of finding the sparsest spanner of a given directed graph G on n vertices. A spanner of a graph is a sparse ...

Sparse Networks Tolerating Random Faults
A network G is called random-fault-tolerant (RFT) network for a network G if G contains a fault-free isomorphic copy of G with high probability even if each processor fails indepe...
