Hello,

I am trying to solve a linear problem using GLPK. I have already found a solution but I would like to know which method is being used by GLPK to solve the LP problem.

My call is:

```
model = Model(GLPK.Optimizer)
# Set variables and constraints
JuMP.optimize!(model)
```

Does JuMP tell GLPK to solve the problem using Simplex method by default? Does GLPK decide which method it will use?

Thanks in advance,
