On a Total Version of 1-2-3 Conjecture
Discussiones Mathematicae Graph Theory, 2020 A total k-coloring of a graph G is a coloring of vertices and edges of G using colors of the set {1, . . . , k}. These colors can be used to distinguish adjacent vertices of G. There are many possibilities of such a distinction.

Group twin coloring of graphs [PDF]
Discrete Mathematics & Theoretical Computer Science, 2018 For a given graph $G$, the least integer $k\geq 2$ such that for every Abelian group $\mathcal{G}$ of order $k$ there exists a proper edge labeling $f:E(G)\rightarrow \mathcal{G}$ so that $\sum_{x\in N(u)}f(xu)\neq \sum_{x\in N(v)}f(xv)$ for each edge ...

Improving Satellite Retrieval of Coastal Aquaculture Pond by Adding Water Quality Parameters
Remote Sensing, 2022 Coastal aquaculture is an important supply of animal proteins for human consumption, which is expanding globally. Meanwhile, extensive aquaculture may increase nutrient loadings and environmental concerns along the coast.

On the Total-Neighbor-Distinguishing Index by Sums
Graphs Comb., 2015 We consider a proper coloring c of edges and vertices in a simple graph and the sum f(v) of colors of all the edges incident to v and the color of a vertex v.

Graph Neural Network Recommendation Algorithm Based on Multimodal Fusion [PDF]
Jisuanji gongchengMany existing Graph Neural Network(GNN) recommendation algorithms use the node number information of the user-item interaction graph for training and learn the high-order connectivity among user and item nodes to enrich their representations.

On the Neighbor Sum Distinguishing Index of Planar Graphs [PDF]
Journal of Graph Theory, 2014 Let c be a proper edge coloring of a graph G=(V,E) with integers 1,2,…,k . Then k≥Δ(G) , while Vizing's theorem guarantees that we can take k≤Δ(G)+1 .

Quasi-majority neighbor sum distinguishing edge-colorings [PDF]
Discrete MathematicsIn this paper, a $k$-edge-coloring of $G$ is any mapping $c:E(G)\longrightarrow [k]$. The edge-coloring $c$ of $G$ naturally defines a vertex-coloring $\sigma_{c}: V(G) \to \mathbb{N}$, where $\sigma_{c}(v)=\sum_{u\in N_G(v)}c(vu)$ for every vertex $v\in
