Hello!

I am using JuMP (0.18.4) (with Gurobi as solver) in a script to solve the same optimization problem for different input. This results in the same optimization problem being solved for many times.

Now, everything seems to work, except for the fact that every time the optimization problem is solved for a certain input set, something like the following is printed in the REPL:

Warning for adding constraints: zero or small (< 1e-13) coefficients, ignored

Optimize a model with 15 rows, 76 columns and 122 nonzeros

Coefficient statistics:

Matrix range [1e+00, 1e+00]

Objective range [1e+00, 1e+00]

Bounds range [2e+02, 1e+04]

RHS range [0e+00, 0e+00]

Iteration Objective Primal Inf. Dual Inf. Time

0 -5.7489940e+04 7.230620e+02 0.000000e+00 0s

9 -5.7489940e+04 0.000000e+00 0.000000e+00 0sSolved in 9 iterations and 0.00 seconds

Optimal objective -5.748994012e+04Solved in 3 iterations and 0.00 seconds

Optimal objective -4.592409418e+04

Now, if this is printed thousands of times, at one point I donâ€™t manage seeing some other information I may have printed beforehand in the REPL and which I may need to visualize later too.

So, my question is: is there a way to completely suppress the aforementioned output from being printed/displayed in the REPL?

By the way, I am using Julia 0.6.4.
