Setting solver option in Jump

[Smaz89]

Hi all,

I'm trying to write my first optimization code using JuMP, after years passed on AMPL. I am not able to set solver options as time limit and solution tolerance; setting also a real-time updating of the solution (with actual solution upper bounds) would be useful for me.

Can anyone give me an hint?

P.s. I usually use GLPK and Gurobi as solvers

Hi @Smaz89. You can set solver options by tacking them onto the solver object:
https://github.com/JuliaOpt/GLPKMathProgInterface.jl

GLPKSolverLP(method=:Exact, presolve=true, msg_lev=GLPK.MSG_ON)

https://github.com/JuliaOpt/Gurobi.jl

GurobiSolver(Method=1, IterationLimit=100.)

The gurobi options match those in the gurobi documentation.
