WebFeb 22, 2024 · Now the graph is an edge-weighted graph so apply Dijkstra’s algorithm to find the shortest path from s to all other vertices. Reduce the problem to normal Dijkstra, which assumes no weights on the vertices. For this, you will need to define w':E->R, a new weight function for edges. WebHowever I can't seem to apply this to my problem. I have a graph with weighted edges, but the weights aren't unique (so there are like 15 edges with weight 1). I want to colour my edges based on the weight they have, the lower the weight the lighter the colour.
