What specific errors are you encountering when calling the run_vns() function in the latest commit?

[emillysilva65]

The traceback indicates a type mismatch when passing the solution object into run_vns(), specifically failing at the initial local search phase. Are you seeing this null pointer exception consistently when the neighborhood structure is initialized, or is it triggered only by the current heuristic parameters?

To narrow down the type mismatch in run_vns(), can you provide the output of type(solution) and the specific line in the local search phase where the null pointer is triggered?
