# Pareto front on Binh and Korn problem using a BiLevel formulation¶

In this example, we illustrate the computation of a Pareto front plot for the Binh and Korn problem. We use a BiLevel formulation in order to only compute the Pareto-optimal points.

## Import¶

The first step is to import some functions from the API, and to configure the logger.

from __future__ import annotations

from gemseo.api import configure_logger
from gemseo.api import create_design_space
from gemseo.api import create_discipline
from gemseo.api import create_scenario
from numpy import array

configure_logger()

<RootLogger root (INFO)>


## Definition of the disciplines¶

In this example, we create the Binh and Korn disciplines from scratch by declaring their expressions and using the AnalyticDiscipline.

expr_binh_korn = {
"obj1": "4*x1**2 + 4*x2**2",
"obj2": "(x1-5.)**2 + (x2-5.)**2",
"cstr1": "(x1-5.)**2 + x2**2 - 25.",
"cstr2": "-(x1-8.)**2 - (x2+3)**2 + 7.7",
}


This constraint will be used to set obj1 to a target value for the lower-level scenario.

expr_cstr_obj1_target = {"cstr3": "obj1 - obj1_target"}


## Instantiation of the disciplines¶

Here, we create the disciplines from their expressions.

discipline_binh_korn = create_discipline(
"AnalyticDiscipline", expressions=expr_binh_korn
)
discipline_cstr_obj1 = create_discipline(
"AnalyticDiscipline", expressions=expr_cstr_obj1_target
)


## Definition of the lower-level design space¶

design_space = create_design_space()

disciplines = [
discipline_binh_korn,
discipline_cstr_obj1,
]


## Creation of the lower-level scenario¶

This scenario aims at finding the obj2 optimal value for a specific value of obj1.

scenario = create_scenario(
disciplines,
"DisciplinaryOpt",
design_space=design_space,
objective_name="obj2",
)

scenario.default_inputs = {"algo": "NLOPT_SLSQP", "max_iter": 100}


We add the Binh and Korn problem constraints.

scenario.add_constraint("cstr1", "ineq")


We add a constraint to force the value of obj1 to obj1_target.

scenario.add_constraint("cstr3", "eq")


An MDOScenarioAdapter is created to use the lower-level scenario as a discipline. This newly created discipline takes as input a target obj_1, and returns obj1, obj2 and cstr3. The latter variable is used by the upper level scenario to check if obj1 = obj1_target at the end of the lower-lever scenario execution.

scenario_adapter = MDOScenarioAdapter(
scenario, ["obj1_target"], ["obj1", "obj2", "cstr3"]
)
design_space_doe = create_design_space()
"obj1_target", l_b=array([0.1]), u_b=array([100.0]), value=array([1.0])
)


## Creation of a DOEScenario¶

Create a DOE Scenario, which will take as input the scenario adapter. It will perform a DOE over the obj1_target variable. Note that obj2 shall be added as an observable of scenario_doe, otherwise it cannot be used by the ParetoFront post-processing.

scenario_doe = create_scenario(
formulation="DisciplinaryOpt",
objective_name="obj1",
design_space=design_space_doe,
scenario_type="DOE",
)


## Run the scenario¶

Finally, we run a full-factorial DOE using 100 samples and we run the post-processing.

run_inputs = {"n_samples": 50, "algo": "fullfact"}
scenario_doe.execute(run_inputs)
scenario_doe.post_process(
"ParetoFront", objectives=["obj1", "obj2"], save=False, show=True
)
