OMMX adapter for Python-MIP
This package provides an adapter for the Python-MIP from/to OMMX
Python-MIP as a solver in OMMX toolchain

Usage
ommx-python-mip-adapter can be installed from PyPI as follows:
pip install ommx-python-mip-adapter
Python-MIP can be used through ommx-python-mip-adapter by using the following:
from ommx_python_mip_adapter import OMMXPythonMIPAdapter
from ommx import Instance, DecisionVariable
x1 = DecisionVariable.integer(1, lower=0, upper=5)
ommx_instance = Instance.from_components(
decision_variables=[x1],
objective=x1,
constraints={},
sense=Instance.MINIMIZE,
)
# Create `ommx.Solution` from the `mip.Model`
ommx_solution = OMMXPythonMIPAdapter.solve(ommx_instance)
print(ommx_solution)
You can get ommx.Instance from a Python-MIP model as the following:
import mip
import ommx_python_mip_adapter as adapter
model = mip.Model()
x1 = model.add_var(name="1", var_type=mip.INTEGER, lb=0, ub=5)
x2 = model.add_var(name="2", var_type=mip.CONTINUOUS, lb=0, ub=5)
model.objective = -x1 - 2 * x2
model.add_constr(x1 + x2 - 6 <= 0)
ommx_instance = adapter.model_to_instance(model)
print(ommx_instance)
