A social network graph partitioning algorithm based on double deep Q-Network [PDF]

open access: yesScientific Reports
With the rapid expansion of social networks, efficiently mining and analyzing massive graph data has become a fundamental challenge in social network research. Graph partitioning plays a pivotal role in enhancing the performance of such analyses. However,

On the activities and partitions of the vertex subsets of graphs [PDF]

open access: yesEnumerative Combinatorics and Applications, 2021
Crapo introduced a construction of interval partitions of the Boolean lattice for sets equipped with matroid structure. This construction, in the context of graphic matroids, is related to the notion of edge activities introduced by Tutte. This implies that each spanning subgraph of a connected graph can be constructed from edges of exactly one ...

Vertex partitions of chordal graphs [PDF]

open access: yesJournal of Graph Theory, 2006
AbstractA k‐tree is a chordal graph with no (k + 2)‐clique. An ℓ‐tree‐partition of a graph G is a vertex partition of G into ‘bags,’ such that contracting each bag to a single vertex gives an ℓ‐tree (after deleting loops and replacing parallel edges by a single edge).

Vertex colouring edge partitions

open access: yesJournal of Combinatorial Theory Series B, 2005
Suppose that the edges of a graph are assigned labels from a \(k\)-set, or equivilently, the edges are partitioned into \(k\) parts. Each vertex \(v\) has an associated multiset \(X_v\) consisting of the labels on its incident edges. The partition is a (proper) vertex coloring if for every edge \(uv\), \(X_u \neq X_v\).

Vertex Partitions of Hypercubes into Symmetric Snakes

open access: yesElectronic Notes in Discrete Mathematics, 2002
Abstract In his paper (Combinatorica 14 (4) (1994), 491-496) Wojciechowski constructed a snake S, i.e. an induces cycle, in the n-dimensional hypercube Qn such that for some subgroup G of the automorphism group of Qn, of order at most 16, the G-translates of S partition the vertex set of Qn.

Some topological indices of pentagonal double chains [PDF]

open access: yesITM Web of Conferences, 2022
In graph theory, lattices are used when some structural part of the graph repeats itself finitely or infinitely many times. They have applications in complex analysis and geometry in mathematics, and also natural applications in chemical graph theory. As

Ordered Vertex Partitioning [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2000
A transitive orientation of a graph is an orientation of the edges that produces a transitive digraph. The modular decomposition of a graph is a canonical representation of all of its modules. Finding a transitive orientation and finding the modular decomposition are in some sense dual problems.

On the Bounded Partition Dimension of Some Generalised Graph Structures

open access: yesJournal of Mathematics, 2022
Consider λ to be a connected graph with a vertex set Vλ that may be partitioned into any partition set S. If each vertex in λ has a separate representation with regard to S and is an ordered k partition, then the set with S is a resolving partition of λ..

$k$-Efficient partitions of graphs [PDF]

open access: yesCommunications in Combinatorics and Optimization, 2019
A set $S = \{u_1,u_2, \ldots, u_t\}$ of vertices of $G$ is an efficient dominating set if every vertex of $G$ is dominated exactly once by the vertices of $S$.
