Degree sequence optimization and extremal degree enumerators

open access: yesDiscrete Applied Mathematics
The degree sequence optimization problem is to find a subgraph of a given graph which maximizes the sum of given functions evaluated at the subgraph degrees. Here we study this problem by replacing degree sequences, via suitable nonlinear transformations, by suitable degree enumerators, and we introduce suitable degree enumerator polytopes.

Largest component of subcritical random graphs with given degree sequence [PDF]

open access: yes, 2023
We study the size of the largest component of two models of random graphs with prescribed degree sequence, the configuration model (CM) and the uniform model (UM), in the (barely) subcritical regime.

The clustering coefficient of a scale-free random graph [PDF]

open access: yes, 2009
We consider a random graph process in which, at each time step, a new vertex is added with m out-neighbours, chosen with probabilities proportional to their degree plus a strictly positive constant.

Packing Tree Degree Sequences [PDF]

open access: yesGraphs and Combinatorics, 2019
AbstractA degree sequence is a list of non-negative integers, $${D = d_1, d_2, \ldots , d_n}$$D=d1,d2,…,dn. It is called graphical if there exists a simple graph G such that the degree of the ith vertex is $$d_i$$di; G is then said to be a realization of D. A tree degree sequence is one that is realized by a tree.

Optimization over Degree Sequences [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 2018
We introduce and study the problem of optimizing arbitrary functions over degree sequences of hypergraphs and multihypergraphs. We show that over multihypergraphs the problem can be solved in polynomial time. For hypergraphs, we show that deciding if a given sequence is the degree sequence of a 3-hypergraph is NP-complete, thereby solving a 30 year ...

Degree Sequence [PDF]

open access: yes, 2019
Teorija grafova je od velikog značaja u različitim područjima znanosti. Jednostavni konačni grafovi predstavljaju značajnu vrstu grafova. U ovom završnom radu se razmatra niz stupnjeva konačnog jednostavnog grafa, pojam usko vezan uz osnovne elemente ...

On the necessity of Chvátal’s Hamiltonian degree condition

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
In 1972 Chvátal gave a well-known sufficient condition for a graphical sequence to be forcibly Hamiltonian, and showed that in some sense his condition is best possible.

The irregularity of two types of trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2016
The irregularity of a graph $G$ is defined as the sum of weights $|d(u)-d(v)|$ of all edges $uv$ of $G$, where $d(u)$ and $d(v)$ are the degrees of the vertices $u$ and $v$ in $G$, respectively.
