Key features of this model:
- Description: Minimize 3D polynomial with multiple local optima.
- Category: Non-linear functions.
- Type: Non-convex MINLP.
- Library: Pyomo.
- Solver: Couenne.
- The source article describes how to install the Couenne solver on Windows, then presents an example of solving a model using Pyomo and Couenne.
- There is a brief discussion of specifying options for the Couenne solver. For some solvers, options can be specified directly within the Python code. However, that does not work with Couenne, so an external options file must be used. We include an example of an options file, which must be in the same folder as the program.
