[Help-glpk] GLPSOL - Matrix generation elapse time

[Noli Sicad]

Hi,

I observed lately that the time displayed (i.e. Time used) in glpsol
logs is time used in solving the matrix.

Example (below).

~~~~~~
.
Constructing initial basis...
Size of triangular part = 579
*     0: obj =   2.315150579e+07  infeas =  0.000e+00 (0)
*   444: obj =   2.626836994e+08  infeas =  0.000e+00 (0)
OPTIMAL SOLUTION FOUND
Time used:   0.0 secs
Memory used: 33.5 Mb (35126659 bytes)
====================================

My MathProg models take time to generate the matrix. It ranges from 5
minutes to 20 minutes depending on how I formulated the constraints
and reports (i.e. writing CSV files).

Andrew, would it be possible in the next release of GLPK/MathProg to
include time elapse for matrix generation in glpsol as part of the
logs?

Xypron, et. al, how to do I create a MathProg script to track down
times, glpsol session?

E.g.

1. Start the glpsol
2. End the glpsol
3. Total time in glpsol session (e.g. in minutes and seconds)

Thanks.

Noli
