I have begun using the "proximity search" option (--proxy) and set for 120 seconds. On the problem that I'm solving, it is doing an outstanding job of getting solutions within 10% (and sometimes even within 1%) of optimal. [It might take GLPK 30-60 minutes longer to obtain provably optimal results.] It's speeding up my solution times considerably.
I am very impressed with this option. Good job Andrew. And thanks to Prof Fischetti and Michele Monaci for providing the original research. -Marc ________________________________ This e-mail and any attachments may be confidential or legally privileged.
