Hi,
I am using GLPK to solve some linear programming models.
The model size is 200k variables and has one constraint.
It took GLPK 13 minutes to load data and build the LP model.
But, it took GLPK 17 minutes to solve it.
Is it normal ? Why building a model took so long time ?
Also, when GLPK is solving the model, it print out the detailed process of solving model on the command line terminal.
How to make GLPK to solve the model silently without printing anything on terminal ?
