pyomo-ripopt
Pyomo solver plugin for ripopt, a fast interior-point NLP solver written in Rust.
Installation
pip install pyomo-ripopt
This installs the solver plugin and a bundled ripopt binary. No Rust toolchain needed.
Usage
import pyomo_ripopt # registers the solver
from pyomo.environ import *
model = ConcreteModel()
model.x = Var(initialize=0.5)
model.obj = Objective(expr=(model.x - 2)**2)
solver = SolverFactory('ripopt')
result = solver.solve(model, tee=True)
print(f"x* = {value(model.x)}") # 2.0
Solver Options
Pass options the same way as Ipopt:
solver = SolverFactory('ripopt')
solver.options['max_iter'] = 1000
solver.options['tol'] = 1e-10
solver.options['print_level'] = 5
Building from Source
If a pre-built wheel is not available for your platform:
cargo install ripopt # installs the ripopt binary
pip install pyomo-ripopt --no-binary :all:
The solver will find the ripopt binary on your PATH.
License
EPL-2.0, same as ripopt.
