I just found out that Giorgio Sartor wrote the GLPK implementation of the 
proximity search while he was an assistant researcher under Prof. Fischetti.  
Well done Giorgio!

Subject: [Help-glpk] Bravo on Proximity Search

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
