Dear all,

I have a big size problem to be solved in GLPK (around 400000 rows and 1 
million columns). The last simulation I run to solve this problem, I got a 
segmentation fault because of the size of the problem. I was wondering if it is 
possible to give to GLPK an initial solution to the problem I am trying to 
solve so that the number of iterations the solver has to do afterwards is 
decreased, and be able to get a solution.

Is this possible? how would be the way to do it? I didn't see this  explained 
online or in the user's manual.

Moreover, do you think decreasing the tolerance would help in this case?

Many thanks,

Juan
