Weighted Domination of Independent Sets [PDF]

open access: yesGraphs and Combinatorics, 2019
The {\em independent domination number} $γ^i(G)$ of a graph $G$ is the maximum, over all independent sets $I$, of the minimal number of vertices needed to dominate $I$. It is known \cite{abz} that in chordal graphs $γ^i$ is equal to $γ$, the ordinary domination number.

Counting Independent Sets in Cocomparability Graphs [PDF]

open access: yes, 2019
We show that the number of independent sets in cocomparability graphs can be counted in linear time, as can counting cliques in comparability graphs. By contrast, counting cliques in cocomparability graphs and counting independent sets in comparability ...

Independent sets in the hypercube revisited [PDF]

open access: yes, 2020
We revisit Sapozhenko's classic proof on the asymptotics of the number of independent sets in the discrete hypercube $\{0,1\}^d$ and Galvin's follow-up work on weighted independent sets.

Fibonacci number of the tadpole graph

open access: yesElectronic Journal of Graph Theory and Applications, 2014
In 1982, Prodinger and Tichy defined the Fibonacci number of a graph G to be the number of independent sets of the graph G. They did so since the Fibonacci number of the path graph Pn is the Fibonacci number F(n+2) and the Fibonacci number of the cycle ...

Extremal Independent Set Reconfiguration

open access: yesThe Electronic Journal of Combinatorics, 2023
The independent set reconfiguration problem asks whether one can transform one given independent set of a graph into another, by changing vertices one by one in such a way the intermediate sets remain independent. Extremal problems on independent sets are widely studied: for example, it is well known that an $n$-vertex graph has at most $3^{n/3 ...

Note on independent sets of a graph [PDF]

open access: yes, 1994
summary:Let the number of $k$-element sets of independent vertices and edges of a graph $G$ be denoted by $n(G,k)$ and $m(G,k)$, respectively. It is shown that the graphs whose every component is a circuit are the only graphs for which the equality $n(G ...

Approximation Algorithms for Graph Partition into Bounded Independent Sets

open access: yesTsinghua Science and Technology, 2023
The partition problem of a given graph into three independent sets of minimizing the maximum one is studied in this paper. This problem is NP-hard, even restricted to bipartite graphs.
