Analyzing customer transactions to discover high-utility itemsets is a popular
task, which consists of finding the sets of items that are purchased together
and yield a high profit. However, many studies assume that transactional data is
static while in real-life, it changes over time. For example, the unit profits
of items may vary from one week to another because sale prices and production
costs... hiện toàn bộ

In this paper, we study crucial elements of a complex network, namely its nodes
and connections, which play a key role in maintaining the network's structure
and function under unexpected structural perturbations of nodes and edges
removal. Specifically, we want to identify vital nodes and edges whose failure
(either random or intentional) will break the most number of connected triples
(or triang... hiện toàn bộ
