In many cases, even though the shortest path length of two nodes is rather larger, their interaction influence is also significant if the number of shortest paths between them is considerable. Inspired by this fact, the authors propose an improved centrality index (ICC) based on well-known ...
let us choose any two of these nodes. Without loss of generality, choose the nodev_{11}from the first level and the nodev_{n+2,2n+3}from the(n+2)^{th}level.

These measures consider that information travels throughout all possible paths between two researchers, like cascade analysis in information diffusion studies [27]. As a result, the influence that researchers have over each other is calculated. Another contribution is the modeling of a scientific ...

On the other hand, a data network also provides the functionality of a virtual reliable connection (such as a TCP-based connection); thus, routing information can be exchanged using such a virtual connection between any two nodes. The rest of the discussion in this section mostly centers ...

Instead, it refers to a set of vertices (that is, points or nodes) and of edges (or lines) that connect the vertices. When any two vertices are joined by more than one edge, the graph is called a multigraph. A graph without loops and with at most one edge between any two vertices...
Each sub-problem is an elementary shortest-path problem with resource constraints. The path starts at the artificial start node (depot) and to the artificial end node (depot) in the route graph. The route graph and its construction are explained in the following sections. Solving each sub-...
The betweenness centrality [22] is the ratio of the number of edges passing through a node in the shortest paths to the number of all shortest paths in the network. In a weighted network, the path length between the nodes is determined by the edge weight. In the process of infectious ...
