<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I’m working in a OR solution for a scheduling media
plan, the scenarios it’s a huge with 100000 of binary variables and
constraints, I’m using FLOPC++ with solvers that currently I’m
using it’s: GLPK, SYMPHONY, CBC and OSL, I’m a very to worry about
time solution, because the one day of processing don’t return a good
solution and I will consider to use ILOG CPLEX to do this. I want know if GLPK
or SYMPHONY can resolve a huge problem like this with good feasible time,
because I have many reasons to use Free Software. The development machine is a
Intel P4 3.0GHz, L2 1024MB and 2GB RAM, with a 4000 variables and 1015 constraints
using GLPK solver the solution occurs in 4137 seconds, it’s the best
result in all those solvers that I’m using. Another question, Can flopc
lib has a control about time limit or gap of solutions found for GLPK and
SYMPHONY? I need specify a time limit but in a flopc++ framework I not found
how I can do this.<o:p></o:p></span></font></p>
