The complexity of combinatorial optimization problems on d‐dimensional boxes [PDF]

open access: yes, 2007
The Maximum Independent Set problem in d-box graphs, i.e., in intersection graphs of axis-parallel rectangles in R-d, is known to be NP-hard for any fixed d >= 2.

Distributed Approximation of Maximum Independent Set and Maximum Matching [PDF]

open access: yesProceedings of the ACM Symposium on Principles of Distributed Computing, 2017
We present a simple distributed $Δ$-approximation algorithm for maximum weight independent set (MaxIS) in the $\mathsf{CONGEST}$ model which completes in $O(\texttt{MIS}(G)\cdot \log W)$ rounds, where $Δ$ is the maximum degree, $\texttt{MIS}(G)$ is the number of rounds needed to compute a maximal independent set (MIS) on $G$, and $W$ is the maximum ...

Hardness of the maximum-independent-set problem on unit-disk graphs and prospects for quantum speedups

open access: yesPhysical Review Research, 2023
Rydberg atom arrays are among the leading contenders for the demonstration of quantum speedups. Motivated by recent experiments with up to 289 qubits [Ebadi et al., Science 376, 1209 (2022)0036-807510.1126/science.abo6587], we study the maximum ...

On the number of maximum independent sets of graphs [PDF]

open access: yesTransactions on Combinatorics, 2014
Let $G$ be a simple graph. An independent set is a set of pairwise non-adjacent vertices. The number of vertices in a maximum independent set of $G$ is denoted by $alpha(G)$. In this paper, we characterize graphs $G$ with $n$ vertices and with maximum

Beyond Maximum Independent Set: An Extended Integer Programming Formulation for Point Labeling

open access: yesISPRS International Journal of Geo-Information, 2017
Map labeling is a classical problem of cartography that has frequently been approached by combinatorial optimization. Given a set of features in a map and for each feature a set of label candidates, a common problem is to select an independent set of ...

Towards maximum independent sets on massive graphs [PDF]

open access: yesProceedings of the VLDB Endowment, 2015
Maximum independent set (MIS) is a fundamental problem in graph theory and it has important applications in many areas such as social network analysis, graphical information systems and coding theory. The problem is NP-hard, and there has been numerous studies on its approximate solutions.

Evaluation of Centralized Reader Anti-Collision Protocols for Mobile RFID System Based on Maximum Independent Set: A Simulation Study

open access: yesIEEE Access, 2020
Radio Frequency IDentification (RFID) systems often encounter reader collisions when multiple readers interrogate tags at the same time. Especially in the mobile RFID system, the mobility of readers leads to more reader collisions.

Maximum weight independent set in trees [PDF]

open access: yesBIT, 1987
Computing a maximum independent set, weighted or unweighted, is NP-hard for general as well as planar graphs. However, polynomial time algorithms do exist for solving this problem on special classes of graphs. In this paper we present an efficient algorithm for computing a maximum wehe extent to which, given two categories A and B and a functor K from ...

Finding a Maximum Independent Set in a Sparse Random Graph [PDF]

open access: yes, 2005
We consider the problem of finding a maximum independent set in a random graph. The random graph G is modelled as follows. Every edge is included independently with probability d n, where d is some sufficiently large constant.
