Broadcasting on cactus graphs

M Čevnik, J Žerovnik - Journal of Combinatorial optimization, 2017 - Springer
Broadcasting is the process of dissemination of a message from one vertex (called
originator) to all other vertices in the graph. This task is accomplished by placing a sequence …

[HTML][HTML] The 2-maxian problem on cactus graphs

L Kang, C Bai, E Shan, K Nguyen - Discrete Optimization, 2014 - Elsevier
This paper deals with the 2-maxian problem on cactus graphs. It is shown that in the worst
case the midpoint of any path connecting m 1 and m 2, where {m 1, m 2} is the 2-maxian of …

Integer programming approach to static monopolies in graphs

B Moazzez, H Soltani - Journal of Combinatorial Optimization, 2018 - Springer
A subset M of vertices of a graph is called a static monopoly, if any vertex v outside M has at
least ⌈ 1 2\deg (v) ⌉⌈ 1 2 deg (v)⌉ neighbors in M. The minimum static monopoly problem …
