Subject: Glpsol Changing Tolerance
Date: Thu, 11 Jul 2013 12:05:01 -0500
To whom it may concern,
I'm having a problem with using glpsol to solve an MIP problem using the
default tolerances. Using the MIP variant of my problem glpsol find an
integral optimal solution; however when I take that solution and solve
the problem again with the integer variables converted to parameters the
solution is vastly different. I have had this issue before with
commercial solvers and have solved it by tightening the integrality
tolerance to 0. Unfortunately I cannot determine a way to do this with
glpsol. Any assistance would be appreciated.
