I have asked my students to set a fixed random seed in their experiments with a formulation implementation. Many have used Julia/JuMP as I have incentivized them to do so. However, I was not able to tell them how to set the random seed using Julia/JuMP/GLPK. GLPK has a command-line argument (--seed) for this, but the documentation does not make clear if there is a parameter that you can pass to JuMP that will translate in the equivalent of that flag.
I do not know if there its a way to do this with GLPK.
Does --seed actually do anything? The documentation implies that this only applies to models in the GNU MathProg modeling format.
Tell them to use HiGHS instead:
