Worse performance with version 0.3.0

[wdscoelhopasqal]

When I run this code I could find the optimal solution with MIS solver v=0.2.3, now with the version 0.3.0 I cannot find any good solution.

from mis import MISSolver, MISInstance, SolverConfig, BackendConfig, BackendType, MethodType
import networkx as nx
import my_functions as mf

my_cloud_credentials = mf.get_cloud_credentials("my_cloud_credentials.txt")
G = nx.Graph([(4, 9), (4, 10), (5, 6), (5, 7), (6, 7), (9, 10)])
G.add_nodes_from([1,2,3,8])
config = SolverConfig(
    backend = BackendConfig(
        backend=BackendType.QUTIP,#
        username=my_cloud_credentials["username"],
        project_id=my_cloud_credentials["project_id"],
        password=my_cloud_credentials["password"]
    ),
    method = MethodType.EAGER,
    max_iterations=1,
    preprocessor=None,
    postprocessor=None
)
instance = MISInstance(G)

# Run the solver
solver = MISSolver(instance, config)
solutions = solver.solve()

# Display results
print("MIS solution:", solutions[0].nodes)
print("Solution frequency:", solutions[0].frequency)
solutions[0].draw()

Since that's without the pre/post-processor, before 0.3.0, this would have been essentially random, due to #119.

@wdscoelhopasqal Have you tried drawing more than the first solution?

Yeap, I got 5 of them if I remember correctly, none of those was close to a good solution (in terms of size)
