Could you give some more details? The title of the thread doesn’t seem to have anything to do with your question.

Are you using JuMP? Here’s the section of the docs describing how to query an objective function:

If your question is really about the `Read a CSV` part, then there are various tutorials in the JuMP documentation that will help:

- [Getting started with data and plotting · JuMP](https://jump.dev/JuMP.jl/stable/tutorials/getting_started/getting_started_with_data_and_plotting/)
- [The factory schedule example · JuMP](https://jump.dev/JuMP.jl/stable/tutorials/linear/factory_schedule/)
