A published network graph with k-anonymous path privacy has at least k indistinguishable shortest paths between the source and destination vertices [21]. In order to achieve such privacy, three different strategies of modification on edge weights of directed graphs are proposed. Numerical comparisons ...

You need two data structures for Dijkstra’s algorithm — a weighted graph and a min heap. The only change you need is the Node struct in the weighted graph, toadd a through pointer to a Node . This field, when not nil, points to the previous node in the shortest path: typeNodestruc...
P = shortestpath(G,s,t,'Method',algorithm) optionally specifies the algorithm to use in computing the shortest path. For example, if G is a weighted graph, then shortestpath(G,s,t,'Method','unweighted') ignores the edge weights in G and instead treats all edge weights as 1. example ...

First thanks for a lot of useful information provided here. I had 2 questions regarding the average shortest path in weighted graph, particluary if there’s a similar way to compute Diameter of graph and also to display a distribution of shortest paths (in a way like “what is the probabil...
