Can you impove Dijkstra's time complexity by not filling completely the priority queue?

I have found two diferent aproaches to Dijkstra's priority queue.
Shouldn't the time complexities be different?

Normal implementation of Dijkstra with priority queue

The implementation you usually find for Dijkstra's shortest path starts filling the priority queue with ALL vertices:
(From wikipedia's pseudocode:)

The log function grows slowly. Even with a road network, where you might have on the order of n^1/3 to n^1/2 nodes on the frontier, the log factor is still at least log n^1/3 = (1/3) log n = Θ(log n), so you're not seeing an asymptotic savings.

For road networks specifically, there are improvements that are way more consequential, e.g., reach and contraction hierarchies.

Asked 2020-Jun-28 at 23:48

I'm trying to do a fibonacci heap, and I don't understand why I get an "indexofboundsException" error in the consolidate method, I implement it just like geek_for_geeks, although it is in C language, I am doing it in java, and it should work :(.

As I was saying, I am trying to do the implementation to eliminate the minimum of fibonacci heap, the insertion was successful, the display also, but the consolidate, I get an error in the array:

There is an error in the original C code that you’re repeating in Java. Specifically, look at your adapted Java code:
