Hi Andrew,

I checked with the GLPK source code, but didn't find anything useful in this 
regard. I wonder if we can add another option to the glpsol (and some thing in 
the solver control structure in the API), about specifying an objective value 
to an MIP problem obtained via some heuristics, in the hope to speed it up. 
This kind of option is available to cplex, I think, and it is probably helpful 
in some cases.

Thanks,

Yingjie
