I am trying to use the DualDecomposition package to solve the farmer test case. The `@show DD.primal_solution(algo)` just shows the solution for the CROPS variables. How could I show all variables including CROPS, PURCH, and SELL?

Thank you for your time.

Hi @Ethan_Tran

I assume you’re referring to [GitHub - kibaekkim/DualDecomposition.jl: An algorithmic framework for parallel dual decomposition methods in Julia](https://github.com/kibaekkim/DualDecomposition.jl)?

I dont know if Kibaek reads this forum. You might have more luck opening a GitHub issue.
