Is there a python module somewhere (been searching today, no luck)
which has efficiently coded various graph-handling routines, such as
finding the shortest path through a graph, or the set of all paths
through a graph? I'm not a compsci-educated person, so coding my own
would be less parsimonious.
Thanks for any suggestions!

Is there any interest in a (hypothetical) standard graph API (with
'graph' meaning a network, consisting of nodes and edges)? Yes, we
have the standard ways of implementing graphs through (e.g.) dicts
mapping nodes to neighbor-sets, but if one wants a graph that's
implemented in some other way, this may not be the most convenient (or
abstract) interface to emulate. It might be nice to have the kind of
polymorphic freedom that one has with,...

I'm working on an image segmentation algorithm. An essential part of the
algorithm is a graph to keep track of the connectivity between regions.
At the moment I have a working implementation, but it's not flexible
enough anymore and I need something more advanced. I already have a data
structure in mind, but I don't know how to implement that nicely in C++.

Hi All,
Currently I am working on a generic graph library so I can do various
graph based analysis for various projects I have ideas for. Currently
I am implementing Graph as a wrapper around a dictionary. Currently my
implementation works like this:
t = Graph()
n1 = Node("Node1")
n2 = Node("Test2")

I need to represent the hyperlinks between a large number of HTML
files as a graph. My non-directed graph will have about 63,000 nodes
and and probably close to 500,000 edges.
I have looked into igraph (http://cneurocvs.rmki.kfki.hu/igraph/doc/
python/index.html) and networkX (https://networkx.lanl.gov/wiki) for
generating a file to store the graph, and I have also looked into
Graphviz for visualization. I'm just not sure which modules...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
