I got this message for my optimization problem can anybody help me how to resolve this?

Read [Solutions · JuMP](https://jump.dev/JuMP.jl/stable/manual/solutions/)

You need to check the various statuses to see if a solution exists.

How can I do that?  
I was doing a Stochastic optimization problem with one uncertain variable, that works perfectly. Then I incorporate a second uncertain variable with a different number of scenarios. then I get the message.

> How can I do that?

Follow the examples in the documentation. Use `termination_status(model)` to check if the solver found an `OPTIMAL` solution.

If you’re still struggling after reading the documentation, please provide a reproducible example:

I just follow the example and here is what I get. it returned The model was not solved correctly.

"  
optimize!(ESTMODEL1)  
primal\_status(ESTMODEL1) " NO\_SOLUTION::ResultStatusCode = 0"  
if termination\_status(ESTMODEL1) == MOI.OPTIMAL  
optimal\_solution = value.(Z2)  
optimal\_objective = objective\_value(ESTMODEL1)

elseif termination\_status(ESTMODEL1) == MOI.TIME\_LIMIT && has\_values(ESTMODEL1)  
suboptimal\_solution = value.(Z2)  
suboptimal\_objective = objective\_value(ESTMODEL1)  
else  
error(“The model was not solved correctly.”)  
end  
termination\_status(ESTMODEL1::Model) " INFEASIBLE\_OR\_UNBOUNDED::TerminationStatusCode = 6"  
dual\_status(ESTMODEL1::Model) "NO\_SOLUTION::ResultStatusCode = 0  
"

Take another read of the “Please read” post. It describes how to format your code blocks.

The problem seems to be that the termination status was `INFEASIBLE_OR_UNBOUNDED`, which means that your problem doesn’t have a solution to query. You can also see that with the primal status of `NO_SOLUTION`.

If you expected your problem to have a finite optimal solution, then you should double check your formulation for mistakes.

Okey! thank you I am doing that.
