Hi!

I am using the GLPK solver and in the output doesn’t appear the elapsed time:

GLPK Simplex Optimizer, v4.64

0: obj = 0.000000000e+000 inf = 3.846e+001 (1)

3: obj = 1.144956706e+007 inf = 0.000e+000 (0)

- 13: obj = 8.328774553e+006 inf = 0.000e+000 (0)

OPTIMAL LP SOLUTION FOUND

GLPK Integer Optimizer, v4.64

80 rows, 500 columns, 2810 non-zeros

500 integer variables, all of which are binary

Integer optimization begins…

Do you have any idea which command and/or parameter to use to make the elapse time appear?

I really really appreciate your help!
