Re: [Help-glpk] presolving

[Daniele Micarelli]

the problem has no solution because of the constraints: VincStraordinari1 and VincStraordinari2
If i don't consider them, the problem has solution but takes days to find the solution.
There is a procedure to shorten the search? Because I think that GLPSOL almost immediately finds the solution but all this takes time to verify the optimality of this

(p.s. I use the command CUTS for resolve the problem)

Thanks

Hello
I have these two files that i attached

because when i fix these two files with GLPSOL, it used too long (even days) using the commands - math - cuts, and I wanted to know if there are ways of presolving to speed the resolution

thank you very mutch

Best
