- search - A* star algorithm open and closed lists - Stack Overflow
Welcome to StackOverflow Please read and follow the posting guidelines in the help documentation on topic and how to ask apply here In particular, you should supply the implementation you're discussing, and make specific references to the lists in that (pseudo-)code
- A*, whats the best data structure for the open list?
You can combine the hash table and the heap without slow operations showing up Have the hash table map position to index in the heap instead of node Any update to the heap can sync itself (which requires the heap to know about the hash table, so this is invasive and not just a wrapper around two off-the-shelf implementations) to the hash table with as many updates (each O (1), obviously) as
- A* star openlist is not working as expected - Stack Overflow
Concerning performance: First, Consider adding items in the openList to a Set called openSet, as well You can quickly check if an item is in the openList by invoking openSet contains(node)
- priority queue as min heap c++ vs heapq in python (how to convert heapq . . .
The only problem in Visual Studio that pops up in red, is this line currentNode = min_heap pop(openList); as you can see, it says, too many argument for pop How to do it the right way?

I am not sure why this happens and I never explicitly abort threads, so it's a bit of a surprise But I log Exceptions and I am seeing: System Threading ThreadAbortException - Thread was being abo
- Where does Windows store its Open With settings?
I'm trying to programmatically check file associations by the file extension (for example jnlp files) I keep reading that HKEY_LOCAL_MACHINE\\SOFTWARE\\Classes\\JNLPFile\\Shell\\Open\\Command is the
- How do I make my A star search algorithm more efficient?
The seconde one (openNode in openList) is unnecessary when you initialise all g property values with infinity (except the start node) Then you can just compare the new g value with the one that is already stored in the neighbor node Furthermore, I would suggest creating nodes for the whole graph as soon as the graph is created
- a star - A* algorithm open list selection - Stack Overflow
I understand that in the A* algorithm when taking the next step the step with the next lowest predicted cost should be chosen from the openlist or frontier, but when there is multiple lowest steps
