kandi X-RAY | ND-Pyomo-Cookbook Summary
ND Pyomo Cookbook is a collection of notebooks showing how to use Pyomo to solve modeling and optimization problems. With Pyomo, one can embed within Python an optimization model consisting of decision variables, constraints, and an optimization objective. A rich set of features enables the modeling and analysis of complex systems. The notebooks in this collection were developed for instructional purposes at Notre Dame. Originally developed using the Anaconda distribution of Python, the notebooks have been updated to open directly Google Colaboratory where they can be run using only a browser window. PyomoFest at Notre Dame was held June 5-7, 2018. This repository contains the agenda, slides and exercises distributed during that event.

QUESTION
I am pretty new to optimization in general and pyomo in particular, so I apologize in advance for any rookie mistakes.
I have defined a simple unit commitment exercise (example 3.1 from [1]) using [2] as starting point. I got the correct result and my code runs, but I have a few questions regarding how to access stuff.

Answered 2021-Jan-01 at 16:25To answer 1, you can dynamically get the constraint objects from your model using model.component_objects(pyo.Constraint)
which will return an iterator of your constraints, which keeps your from having to hard-code the constraint names. It gets tricky for indexed variables because you have to do an extra step to get the slacks for each index, not just the constraint object. For the duals, you can iterate over the keys
attribute to retrieve those values.
