Minimizing the Spread of Negative Influence in SNIR Model by Contact Blocking

open access: yesEntropy, 2022
This paper presents a method to minimize the spread of negative influence on social networks by contact blocking. First, based on the infection-spreading process of COVID-19, the traditional susceptible, infectious, and recovered (SIR) propagation model ...

Competitive Algorithms for Block-Aware Caching

open access: yesProceedings of the 34th ACM Symposium on Parallelism in Algorithms and Architectures, 2022
Motivated by the design of real system storage hierarchies, we study the block-aware caching problem, a generalization of classic caching in which fetching (or evicting) pages from the same block incurs the same cost as fetching (or evicting) just one page from the block. Given a cache of size k, and a sequence of requests from n pages partitioned into
