pymoo: Setting a starting solution in Pymoo does not work

Hi all,

I want to use a starting solution for pymoo in the algorithms NSGA2. For that I have the following code

intial_solution = ICSimulation.simulateDays_ConventionalControl()
algorithm = NSGA2(
    pop_size=5,
    n_offsprings=2,
    sampling=FloatRandomSampling(),
    crossover=SBX(prob=0.7, eta=20),
    mutation=PM(eta=40),
    eliminate_duplicates=True
)

algorithm.setup(problem, x0=intial_solution )

So i just create an initial_solution by using an external file that returns an x vector that is the vector of decision variables in pymoo for the evalutation. Then I add algorithm.setup(problem, x0=intial_solution ). When adding this line, the algorithm does not seem to terminate or to generally show some outputs. Further, in the evaluation method I can clearly see, that the algorithm, even in the first iteration, does not use the inital_solution as all solutions in the first iteration are just randomly generated as if there is no inital_solution.

So I want to know, how can I tell pymoo to use the inital_solution as a good starting point for the optimization instead of just radomly initiallyzing the inital solutions?
