algorithmic modeling for Rhino
SpiderWeb is a .NET library providing functionality for preforming calculations on graphs. The library is created with a special focuse on the integration of graphs and graph related theroies (e.g. SpaceSyntax) in parametric design envoirnments. Therefore special Versions are avalible for:
Grasshopper
DesignScript (planned)
Any feedback, questions or critic is welcomed.
General introduction into graph theory
Documentation and samples
.NET documentation for SpiderWebLibrary.dll and GH_SpiderWebLibrary.dll

One more question, does the spider web has a "graph viewer" for representing graph without displaying actual geometry?
Just as in your website as nodes and edges in between?
Would it be possible to get an example for it two?
@2: Please define the longest Path, maybe it is possible with your specific definition. However please read: https://en.wikipedia.org/wiki/Hamiltonian_path, especially the section about NP-complete...

Dear Richard,
Thank you for a quick reply.
Would it be possible to get a simple shortest path example between point A and point B as target?
Also is it possible to find longest path between node A and B?
Thank you,
Tomas
Hello Tomas,
Have you had a look at:
http://www.gbl.tuwien.ac.at/_docs/GrasshopperScriptum/GrasshopperSc...
besides this, I am sorry and currently I don't realy have the time to extend them. However if you have specific questions please post them in discussions, I will be able to help.

Hi,
Is it possible to find spider web example files? The files found on mentioned website seems to be poorly documented. It would be good to have list of gh files as examples.
Thank you richard,
This is really a great tool !
Well it's giving you back a graph which you can use again to compute the shortest path (smallest Distance) between each pair of nodes..
see attached file

Hi Richard,
first thanks a lot for the great plugin!
One really small and (simple) question!
I know that the minimum spanning tree method is giving me the connection of all nodes with a minimum overall lentgh of the network.
But does it give me also the network that connects all the nodes + smallest distance between each nodes?
Danke!

Hi Mark,
will look into the definition. However if the costs are +Infinty this means that now path could be found....

Hey Ken
Hey Richard
I tried to solve the problem described below, using a loop (anemone) and SpiderWeb's ShortestPath...
AllShortestPaths.gh
I guess it should work, but there seems to be a bug in ShortestPath.
Have a look into the definition: u will see that the search finds a path with a cost of +Infinity at the second iteration. But there are quite a lot paths with lower cost...
