Validate Time Complexity of Djikstra-Like Function

I'm in need of a mathematician and computer scientist with expertise in algorithm analysis, particularly in the field of Djikstra-like functions. The primary goal of this project is confirming the time complexity of a Djikstra-like function that has been implemented in Python.

Key Points:
- I'm not looking for the development of a new algorithm, but a detailed analysis and confirmation of the time complexity of the existing one in Python.
- The main purpose of this analysis is to validate the efficiency of the algorithm.
- The results of this analysis are to be used for personal knowledge, rather than for an academic publication or software development.

Ideal Candidates:
- Proficient in algorithm analysis, particularly in Djikstra-like functions.
- Expertise in Python for the implementation and analysis.
- Ability to clearly document and present the results of the time complexity analysis.

Your role will be crucial in confirming the efficiency of this Djikstra-like function, which will help me better understand its performance and potential for optimization.
