Computer search for graceful labeling: a survey [PDF]

open access: yesElectronic Journal of Graph Theory and Applications, 2022
Summary: This paper surveys the main computer search results for finding graceful labeling of trees. The paper is devoted to the memory of Mirka Miller, who made an outstanding contribution to the area of graph labeling.

Relaxed Graceful Labellings of Trees [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2002
A graph $G$ on $m$ edges is considered graceful if there is a labelling $f$ of the vertices of $G$ with distinct integers in the set $\{0,1,\dots,m\}$ such that the induced edge labelling $g$ defined by $g(uv)=|f(u)-f(v)|$ is a bijection to $\{1,\dots,m\}$. We here consider some relaxations of these conditions as applied to tree labellings: 1.

Characterizations of kites as graceful graphs [PDF]

open access: yesCubo
We introduce and study an infinite family of graceful graphs, which we call kites. The kites are graphs where a path is joined with a graph "forming" a kite.

Ordered graceful labellings of the 2-star [PDF]

open access: yesDiscrete Mathematics, 2001
The authors investigate ordered graceful labellings of 2-stars. They give a lower bound on the number of non-equivalent ordered graceful labellings by constructing an exponential number of such labellings. This shows that a conjecture of Cahit is false.

Graceful Labelling for Complete Bipartite Fuzzy Graphs [PDF]

open access: yes, 2017
The concept of fuzzy graceful labelling is introduced. A graph which admits a fuzzy graceful labelling is called a fuzzy graceful graph. Fuzzy graceful labelled graphs are becoming an increasingly useful family of mathematical models for a broad range of

Graceful Labelling: State of the Art, Applications and Future Directions [PDF]

open access: yes, 2011
This paper takes a close look at graceful labelling and its applications. We pay special attention to the famous Graceful Tree Conjecture, which has attracted a lot of interest and engaged many researchers over the last 40+ years, and yet to this day ...

EVEN GRACEFUL LABELLING OF A CLASS OF TREES [PDF]

open access: yes, 2020
A labelling or numbering of a graph G with q edges is an assignment of labels to the vertices of G that induces for each edge uv a labelling depending on the vertex labels f(u) and f(v).

Osteoarthritis medical labelling and health-related quality of life in the general population. [PDF]

open access: yesHealth Qual Life Outcomes, 2014
Background: Osteoarthritis is the most common chronic joint disease. In the absence of an effective medical treatment and due to the chronic nature of this condition, an osteoarthritis medical diagnosis may finally result in decreased health-related ...
