Mind the O˜: Asymptotically Better, but Still Impractical, Quantum Distributed Algorithms

open access: yesAlgorithms, 2023
We present two algorithms in the quantum CONGEST-CLIQUE model of distributed computation that succeed with high probability: one for producing an approximately optimal Steiner tree, and one for producing an exact directed minimum spanning tree, each of ...

Random clustering analysis in deterministic DG-based distribution planning

open access: yesEnergy Reports, 2023
New feeders’ allocation, new lines connecting the substations to new feeders and other feeders to tie-line routes, should be defined for minimizing the costs of new facilities’ installation with some limitations as voltage loss, capacity of current ...

Energy Efficient Cluster Head Selection in Internet of Things Using Minimum Spanning Tree (EEMST)

open access: yesApplied Artificial Intelligence, 2021
Internet of things network lifetime and energy issues are some of the most important challenges in today’s smart world. Clustering would be an effective solution to this, as all nodes would be arranged into virtual clusters, while one node will serve as ...

The Diameter of the Minimum Spanning Tree of a Complete Graph [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
Let $X_1,\ldots,X_{n\choose 2}$ be independent identically distributed weights for the edges of $K_n$. If $X_i \neq X_j$ for$ i \neq j$, then there exists a unique minimum weight spanning tree $T$ of $K_n$ with these edge weights.
