哈林图的偶匹配可扩性(Bipartite matching-extendability of Halin graphs)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2009
Let G be a connected graph containing a perfect matching. G is said to be bipartite matching extendable if every matching M of G whose induced subgraph is a bipartite matching extends to a perfect matching of G. The main result is as follows: Halin graph

Enumerating Maximal Induced Subgraphs

open access: yes, 2020
Given a graph $G$, the maximal induced subgraphs problem asks to enumerate all maximal induced subgraphs of $G$ that belong to a certain hereditary graph class. While its optimization version, known as the minimum vertex deletion problem in literature, has been intensively studied, enumeration algorithms are known for a few simple graph classes, e.g ...

On Sequential Heuristic Methods for the Maximum Independent Set Problem

open access: yesDiscussiones Mathematicae Graph Theory, 2017
We consider sequential heuristics methods for the Maximum Independent Set (MIS) problem. Three classical algorithms, VO [11], MIN [12], or MAX [6] , are revisited. We combine Algorithm MIN with the α-redundant vertex technique[3].

Hamilton cycles in almost distance-hereditary graphs

open access: yesOpen Mathematics, 2016
Let G be a graph on n ≥ 3 vertices. A graph G is almost distance-hereditary if each connected induced subgraph H of G has the property dH(x, y) ≤ dG(x, y) + 1 for any pair of vertices x, y ∈ V(H).

Some Variations of Perfect Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2016
We consider (ψk−γk−1)-perfect graphs, i.e., graphs G for which ψk(H) = γk−1(H) for any induced subgraph H of G, where ψk and γk−1 are the k-path vertex cover number and the distance (k − 1)-domination number, respectively.
