Each line segment of a distance-time graph represents one part of a journey. A distance-time graph, sometimes referred to as a travel graph, is a way of representing a journey. It is helpful to have ...

Graph matching and edit distance algorithms form a cornerstone of modern computational techniques used to quantify the similarity between structured data. These methods underpin a wide array of ...

Abstract. In the present paper we are interested in the study of the distance Laplacian eigenvalues of a connected graph with fixed order n and chromatic number χ. We prove lower bounds on the ...

Abstract. We investigate a new graph invariant named reciprocal product–degree distance, defined as: R D D ∗ = ∑ { u , v } ⊆ V ( G ) u ≠ v deg ( u ) ⋅ deg ...
