Undirected graph abstraction
I have an undirected weighted graph and I need to formally describe it.
Abstraction via automata or labelled transition systems seems to be not defined for undirected graphs,
only directed graphs are covered.
States within the graph are dependent on…

Modifying Dijkstra's Algorithm to find shortest path with largest weighting
I'm in need of a piece of code that finds the shortest path between nodes with the greatest weighting. For example, the quickest route from A to D, but with the greatest weighting:
- B- --E
/ \ /
A D
\ / \
C - -F
So right…

Where to do "huge" graph calculations - Flutter, php
I'm planning on doing an application that create the shortest possible path to some interest points.
Each point is an activity separated from the other by a distance (e.g. p1 --50m--> p2). Later there will be a wait time for each point so it'll…
