Re: [Help-glpk] use GLPK to solve LP without printing anything on terminal

[usa usa]

Also,

How to indicate algorithms in GLPK to solve LP or IP from API ?

GLPK has simplex, primal-dual and branch-bound algorithms, are there others?

thanks

If you are using the API then the output is controlled with GLP_ON and GLP_OFF. If you are using mathprog & glpsol then -y filename will send the output to a file rather than your terminal. If using Linux and you absolutely don't want the output then -y /dev/nul should do you.

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 ?

 

Thanks
