How do I easily calculate the shortest path between two geographical spots on
a map?
The map is divided into zones. So I guess it is possible to use Dijkstra’s
Shortest Path algorithm, but it seems like a lot of work and I am sure that
it has been done many times before.
From (x,y) coordinates I need to place the user in a zone and find the
shortest path to all other zones.
Any suggestions are more than welcome. I would hate to reinvent...

Hi all,
I need recommendation for a very fast shortest path algorithm. The
edges are all directed, positive weights. Dijkstra shortest path will
solve it just fine but the if the graph is not parse then it takes about
O(N^2) where N is the # of vertices, too much for large graphs.
Furthermore, I don't need to know the all the path from a start point to
every other single vertex as Dijkstra would provide. Just the shortest
path from a...

I am developing a program using VB.NET that will accept a start and end
point, the system then will generate the shortest path to reach the end
point. Anyone here have idea on doing this or some code examples that can
share it with me?
Thanks in advance.

Hi all,
I am in shortage of time...and i want to know if someone has a code
written in c++ or c for finding the shortest path using stack or
queue??????my specifications r as follow:
Input data:
n = integer number representing the number of vertices
k = small integer number representing the maximal vertex degree
G = unoriented labeled connected graph G with n vertices and maximal
degree k

Hello. I have implemented the Dijkstra shortest path algorithm, it
works fine but I have one question on how I can improve something.
I want to find all the possible shortest paths from a node since there
is a possibility to exist more than one shortest paths with the same
distance.
Does anyone has any idea how this could be done?

Is there any function in networkx which can compute the shortest mean
path length. (Shortest length between all pairs of the nodes in the
graph).
Thanks,

Hi All
Here is a very simple little class for finding a shortest route on a network, following Dijkstra's Algorithm:
#!/usr/bin/env python
#This is meant to solve a maze with Dijkstra's algorithm

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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,...

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...
