If you can iterate effectively over your neighbors, you could say the complexity of your algorithm is even better, namely O ( deg ( S) + deg ( T)). If not, you can still bound it by O ( V) unless you have a multigraph. There might be better algorithms with regard to memory, because your algorithm requires O ( deg ( S) + deg ( T)), for ...

Webnodes when dealing with graph structure information, but knowledge graphs are heterogeneous graphs with different relationships between nodes, so it is difficult to apply GCN directly to knowledge graphs.

A neighbor sum distinguishing (NSD) total coloring ϕ of G is a proper total coloring such that ∑ z ∈ E G ( u) ∪ { u } ϕ ( z) ≠ ∑ z ∈ E G ( v) ∪ { v } ϕ ( z) for each edge u v ∈ E ( G). Pilśniak and Woźniak asserted that each graph with a maximum degree Δ admits an NSD total ( Δ + 3) -coloring in 2015.
