Hello,
I understand that an easy way to make the standard std::priority_queue
stable is by including an integer stamp with each node that is
incremented each time a new node is pushed into the queue. However, no
matter what reasonably-sized type I use for the stamp, eventually the
stamp will 'wrap around' and possibly cause incorrect ordering of
elements. For my application, which queues elements very quickly and
runs for an...

Are priority queues implemented in the STL in Visual Studio 6? If no, which
is the easiest way to simulate them? Multisets?
BTW: The container contains pointers to instances of a class. The ordering
of the elements must follow the value of the class-instances not the value
of the pointers. Furthermore, elements are inserted throughout execution of
the program so I need a insert function which keeps the elements sorted; a
sort function...

else.

Is the STL priority queue a proper implementation of a heap with siftup
algorithm etc ? How do you implement an STL priority queue (link to an
example) ? Is there a resort method, why ?
Thanks

How do you use std::priority_queue to store say an index type (call it
intidx) and sort using another integer type (but smallest weight at the
top) ? How do you pop off the top index ? I mean top() returns the
top element but how do you access the index and the weight.
Is it std::priority_queue <intidx, int>; ? Where does the comparison
fit into it ?

Hello,
I am working with large graphs (~150,000 to 500,000 nodes) which I
need decompose node-by-node, in order of a node's value. A node's
value is determined by the sum of its edge weights. When a node is
removed from the graph, its neighbors' values must be updated to take
into account the removed edges.
I was told to look for a priority queue in Python. I had a look at the
heapq module. It looks like it supports ordering on...

Hello everyone, here is my problem. I have to make a dynamic priority queue,which is a heap, and my book isn't helpful at all, so I have no clues on how to create it.. I read something like a static priority queue, which is an array heap, and for example i/2 is the father of i and so on..
the code of the static priority queue is this:
int i= ++CurrentSize;
while(i != 1 && X > heap) {
// cannot put x in heap
heap = heap; //move...

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...
