CLAIM

https://doi.org/10.1007/978-3-030-61033-3 when this online algorithm is compared with a clairvoyant algorithm achieving the best total value. In this paper, we study a simple and intuitive online algorithm. We analyze its performance in terms of competitive ratio for the general model and a few important variants.

It can be used in almost any broadcast environment, in which the data access frequencies, data sizes, and channel bandwidths can all be non-uniform.

Catherine Crago Blanton,Walt TrybulaG algorithm, we propose an approximation algorithm. We also propose a heuristic algorithm for this special case. For the general case that each node has multiple power levels, we propose a general algorithm NF-MEM-R-G and an approximation algorithm based on NF-MEM-R-G algorithm. We also propose a heuristic algorithm for general case.

A Fast Parallel Algorithm for Finding a Most Reliable Source on a General Ring-Tree Graph with Unrerational probability while all nodes are immune to failures. We first design a complementary dynamic programming algorithm and then develop a parallel algorithm based on the underlying tree for finding an MRS on the network.

Restricted Edge Connectivity of Harary Graphs,nduced by .. A graph . is called ..-optimal if ..(.) = ..(.). A natural question is whether there exists a graph . which is ..-optimal for any . ≤ |.(.)|/2. In this paper, we show that except for two cases, the Harary graph has this property.
