Execute a scenario using a DOE#
from __future__ import annotations
from gemseo import create_discipline
from gemseo import create_scenario
from gemseo.problems.mdo.sobieski.core.design_space import SobieskiDesignSpace
Instantiate the discipline#
discipline = create_discipline("SobieskiMission")
Create the design space#
design_space = SobieskiDesignSpace()
design_space.filter(["y_24", "y_34"])
Create the scenario#
Build scenario which links the disciplines with the formulation and The DOE algorithm.
scenario = create_scenario(
[discipline],
"y_4",
design_space,
maximize_objective=True,
scenario_type="DOE",
formulation_name="DisciplinaryOpt",
)
Execute the scenario#
Here we use a latin hypercube sampling algorithm with 30 samples.
scenario.execute(algo_name="PYDOE_LHS", n_samples=30)
