How to get the path from the Dijkstra algorithm in Python Question: I took the code for the Dijkstra algorithm from this website and rewrote it for my needs (see below). Now I need to implement a feature that would store the shortest path for each node. I tried implementing it using this code from …
Why is the list_comprehension version slower (python)? Are there better ways? Question: I have a line of code, and I’m surprised, that the list comprehended version is slower. I want to calculate "average sphere distances". The steps needed to be done: choose a node chose all elements at a distance "d" around it (shell at …
Heap Dijkstra Implementation is slower than Naive Dijsktra Implementation Question: I have tried to implement the Naive and Heap Dijkstra as shown below but somehow my naive Dijkstra implementation is surprisingly faster. I debugged my code but couldn’t understand where my problem in my implementations are. Why is my heap-based implementation is slower than the …
