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...

implemented Dijkstra's algorithm as follows. plz pour on the negative
criticism cuz I know I have a ton to learn.
oh, before you flame me regarding the language, my class was told to do
this in C# but, what can I say, I just like you guys better than the
crowd in the C# newsgroup. ;o)

This is probably a bit OT, as I'm not looking for a c++ implementaiton of
Dijkstra's algorithm, rather I'm just trying to understand it (is there a
better place then here to ask this question?). I've reviewed several sites
and the faq (no, I'm not asking you to do my homework for me) and the
examples don't give me the information I need to continue on. I'm working
with a complex tree, and am not sure how to logically apply Dijkstra's...

Can somebody please explain and provide pseudocode for the Dijkstra
algorithm?
I'm trying to implement the Dijkstra shortest path algorithm. However, I'm
finding it extremely difficult to understand.
I've a node class that hold the node name, and the x,y coordinate.
I've an edge class the takes two(2) nodes, from and to, and a name for the
edge.
I'm using only simple arrays to store the nodes and the edges, no priority

I've been working on an implementation of Dijkstra's algorithm on and
off for the past few days. I thought I was close to being finished,
but clearly I've done something wrong. I'm not a very experienced
programmer, so please be patient.
My code compiles in g++ without any errors or warnings. Unfortunately
it segfaults when it runs. I tried adding some outputs to the console
throughout the "Dijkstra" function but wasn't able to...

Hey guys,
I'm back, and with another FUN question!
My latest homework asks this question:
"Suppose all the edge weights in a graph are integers between 1 and |E|. How fast can Dijkstra's algorithm be implemented?"
The only thing I could think of is somehow involving bucket sort - since the edges are bounded, we can use bucket sort to achieve an O(n) sorting time - but I'm not sure how I can use the sorted edge weights to help me at...

ONU (Optical Network Unit) is one of the key components for providing high-speed Internet services. Its primary function is to act as an endpoint device located at the user's premises. However, people are often confused as to whether an ONU can Work As a Router. In this blog post, we’ll explore What is ONU, What Is Router, ONU & Router’s main usage, and What is the difference between ONU and Router. Let’s take a closer look !

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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....
