Building the perfect MIPping machine [dual]

Yesterday’s post explained why I prefer to run solver on fast machines over big machines and gave a short example why. In today’s post, I provide some very personal guidelines on how to determine what kind of machine you might need to solve MIPs.  Beware: this post is more based on personal experiences than hard […]

Do you need a bigger computer to solve this MIP? [primal]

When I have difficult time solving a mixed-integer optimization problem (MIP), one of the most common reflexes is to run the problem on a bigger or faster machine.  However, when solving MIPs, throwing more processor power at a problem will not necessarily result in a better solution. Different models require different resources to solve. Overall, using a […]
