This PR adds the foundation for Pyomo integration: pyproject.toml changes: - Add [optimization] extra with pyomo>=6.7.0 and idaes-pse>=2.9.0 - These are optional dependencies, scipy-based code works without them Module structure: - lyopronto/pyomo_models/__init__.py: Placeholder with documentation - tests/test_pyomo_models/__init__.py: Test directory placeholder Installation: pip install .[optimization] # For Pyomo support pip install . # Standard scipy-only installation This enables users to opt-in to Pyomo optimization without affecting existing scipy-based workflows.

Summary
Adds Pyomo as an optional dependency (
pip install lyopronto[optimization]). Creates thelyopronto.pyomo_modelspackage with aPYOMO_AVAILABLEflag and graceful import handling. Pyomo coexists with scipy — both remain available.PR 2 of 7 in the Pyomo integration series.
Changes
lyopronto/pyomo_models/__init__.py— Module init with lazy imports, availability checkpyproject.toml— Add[project.optional-dependencies]foroptimizationextra (pyomo, idaes-pse)tests/test_pyomo_models/__init__.py— Test package initKey Design Decision
Coexistence, not replacement. Installing the
optimizationextra adds Pyomo alongside scipy. The core package works without Pyomo. Code checksPYOMO_AVAILABLEbefore using Pyomo features.PR Chain
Testing
No new tests added. Import test validates graceful fallback when Pyomo is not installed.
